1
00:00:00,000 --> 00:00:05,000
Millions of planets, similar to our own.

2
00:00:05,000 --> 00:00:12,000
The discoveries of exoplanets over the past few years have been absolutely extraordinary,

3
00:00:12,000 --> 00:00:16,000
and many could soon be within the grasp of our technology.

4
00:00:16,000 --> 00:00:22,000
Think about it, civilizations over billions of years could have risen and fallen

5
00:00:22,000 --> 00:00:25,000
even before the Earth was formed.

6
00:00:26,000 --> 00:00:34,000
But if we can reach out and pursue life on other worlds, might they also be reaching out to us?

7
00:00:34,000 --> 00:00:39,000
And have they been doing so for thousands of years?

8
00:00:39,000 --> 00:00:50,000
Could it be that ancient civilizations, ancient aliens from far away migrated from their home worlds and they found Earth?

9
00:00:51,000 --> 00:00:55,000
The implications for humanity are enormous.

10
00:00:57,000 --> 00:01:01,000
There is a doorway in the universe.

11
00:01:01,000 --> 00:01:05,000
Beyond it is the promise of truth.

12
00:01:05,000 --> 00:01:11,000
It demands we question everything we have ever been taught.

13
00:01:11,000 --> 00:01:14,000
The evidence is all around us.

14
00:01:14,000 --> 00:01:18,000
The future is right before our eyes.

15
00:01:18,000 --> 00:01:21,000
We are not alone.

16
00:01:21,000 --> 00:01:24,000
We have never been alone.

17
00:01:32,000 --> 00:01:35,000
Cape Canaveral, Florida.

18
00:01:35,000 --> 00:01:39,000
April 18, 2018.

19
00:01:39,000 --> 00:01:49,000
At 6.51 p.m., a Falcon 9 rocket blasts off on a mission to deploy NASA's newest space telescope into orbit.

20
00:01:49,000 --> 00:01:54,000
The Transiting Exoplanet Survey Satellite, or TESS.

21
00:01:54,000 --> 00:02:04,000
TESS is like a survey of the whole sky, a survey of the nearest hundred light-years or so of planets that would be around these stars.

22
00:02:05,000 --> 00:02:15,000
Over the next decade, scientists expect that TESS will fulfill its primary mission, to discover thousands of so-called exoplanets.

23
00:02:15,000 --> 00:02:20,000
Exoplanets are planets that exist outside of our solar system.

24
00:02:20,000 --> 00:02:24,000
We were certainly in an exoplanet golden age of discovery.

25
00:02:24,000 --> 00:02:29,000
Twenty years ago, we didn't know if there were other Earth-like planets in the universe.

26
00:02:30,000 --> 00:02:36,000
And now we can't imagine how we could discover things at a higher rate and still try to make sense of it.

27
00:02:36,000 --> 00:02:40,000
It's such a struggle just to keep up with the discoveries that we're making right now.

28
00:02:43,000 --> 00:02:48,000
It is only recently, with the development of deep space satellites and high-powered telescopes,

29
00:02:48,000 --> 00:02:56,000
that a more accurate understanding of nearby planets, especially planets capable of supporting human life, has been possible.

30
00:02:57,000 --> 00:03:05,000
But it wasn't so long ago that the notion of Earth-like planets existing in our galaxy wasn't simply unknown.

31
00:03:05,000 --> 00:03:08,000
It was considered blasphemy.

32
00:03:08,000 --> 00:03:17,000
When the 16th century Italian philosopher and cosmologist Giorgiano Bruno expressed his belief in an infinity of worlds

33
00:03:17,000 --> 00:03:21,000
and raised the possibility that other planets could harbor life,

34
00:03:22,000 --> 00:03:26,000
he was charred with heresy and burned at the stake.

35
00:03:26,000 --> 00:03:31,000
It was heretical, revolutionary to believe that there could be alien life out there.

36
00:03:31,000 --> 00:03:36,000
Giorgiano Bruno was burned alive in the streets of Rome.

37
00:03:36,000 --> 00:03:42,000
And what was his crime? To say that they are aliens out there on other planets.

38
00:03:42,000 --> 00:03:45,000
We weren't allowed to think like that.

39
00:03:45,000 --> 00:03:49,000
It challenged all their predispositions and their power structure.

40
00:03:49,000 --> 00:03:52,000
No, there are no other worlds. There's nothing out there.

41
00:03:52,000 --> 00:03:55,000
But there is something out there. There's no question about it.

42
00:03:56,000 --> 00:04:06,000
As recently as the early 1990s, astronomers were still unable to detect these distant planets, even with high-powered telescopes.

43
00:04:06,000 --> 00:04:09,000
It's hard to see an exoplanet.

44
00:04:09,000 --> 00:04:14,000
Imagine trying to look at a firefly next to a spotlight.

45
00:04:14,000 --> 00:04:18,000
It's incredibly difficult because stars shine by their own light.

46
00:04:18,000 --> 00:04:21,000
They give off their own light, but planets reflect light.

47
00:04:21,000 --> 00:04:28,000
A typical star is about 10 billion times brighter than a planet.

48
00:04:29,000 --> 00:04:39,000
Thanks to remarkable advances in technology, astronomers made the very first discovery of an exoplanet in 1992 using an Earth-based telescope.

49
00:04:40,000 --> 00:04:50,000
But that search kicked into high gear in 2009 with the launch of Kepler, the first-based telescope specially designed to find exoplanets.

50
00:04:51,000 --> 00:04:57,000
And in 2018, Kepler was replaced by the even more powerful TESS.

51
00:04:58,000 --> 00:05:08,000
So one of the really cool things about TESS, the new satellite the NASA has put up, is basically it was specifically designed to detect exoplanets.

52
00:05:08,000 --> 00:05:14,000
By what's called the transit method, which is where when a planet goes in front of a star, it blocks the light briefly.

53
00:05:14,000 --> 00:05:17,000
And you really see the light blink on and off.

54
00:05:18,000 --> 00:05:22,000
That telltale dip is what tells you there might be something that's passing in front of it.

55
00:05:22,000 --> 00:05:28,000
The regularity tells you about the orbit, which is the easiest way to actually start looking for new planets.

56
00:05:29,000 --> 00:05:41,000
Although the initial objective in the search for exoplanets was simply to determine how many stars in our galaxy might have planets in orbit around them, the actual results were staggering.

57
00:05:42,000 --> 00:05:46,000
Our galaxy has around 400 billion stars.

58
00:05:46,000 --> 00:05:52,000
From what we've seen so far is on average every star has at least one planet.

59
00:05:52,000 --> 00:05:58,000
So that means that there are 400 billion, at least, planets in our galaxy.

60
00:06:00,000 --> 00:06:04,000
400 billion planets in the Milky Way galaxy alone?

61
00:06:05,000 --> 00:06:13,000
The discovery of such an extraordinary number of exoplanets represents a radical change in our understanding of the universe.

62
00:06:14,000 --> 00:06:24,000
But even more radical is the notion that millions of those planets might actually be capable of not just supporting life, but generating it.

63
00:06:27,000 --> 00:06:35,000
And to that end, astronomers and astrophysicists actively search for planets in a region they refer to as the Goldilocks zone.

64
00:06:36,000 --> 00:06:43,000
The Goldilocks zone is exactly that range for a given star of where water is going to be liquid on a given type of planet.

65
00:06:44,000 --> 00:06:50,000
We want a planet that is not too close, not too far from the mother star, but just right.

66
00:06:50,000 --> 00:07:01,000
Planets that may have oxygen and H2O water that may make possible an atmosphere and maybe even life.

67
00:07:02,000 --> 00:07:11,000
Based upon current observations, scientists are astounded by the number of potentially habitable planets that exist in the Goldilocks zone.

68
00:07:11,000 --> 00:07:24,000
With at least 400 billion planets in our galaxy, if you just look at 1% of that, you're still talking about billions of planets that could potentially be habitable.

69
00:07:25,000 --> 00:07:32,000
This is exciting because we once thought that we were the only game in town that could only exist on the planet Earth.

70
00:07:32,000 --> 00:07:39,000
The discovery of exoplanets, I think it's really changed our view of the potential for life in the universe.

71
00:07:39,000 --> 00:07:46,000
Fundamentally, I think most scientists would now agree that there is some form of life elsewhere in the universe.

72
00:07:47,000 --> 00:07:59,000
But in spite of the abundance of habitable exoplanets, many scientists still cling to the notion that the only kind of life likely to exist outside of Earth is microbial or bacterial.

73
00:07:59,000 --> 00:08:15,000
They are resistant to what they claim are far-fetched notions that these planets might not only contain more sophisticated or evolved life forms, but intelligent life forms, some much more evolved or technologically advanced than our own.

74
00:08:16,000 --> 00:08:27,000
Think about it, the universe is about 13.8 billion years old. The Earth is 4.6 billion years old.

75
00:08:27,000 --> 00:08:35,000
Civilizations over billions of years could have risen and fallen even before the Earth was formed.

76
00:08:36,000 --> 00:08:52,000
Although the realization that the galaxy is teeming with Earth-like planets has triggered a revolution in conventional scientific thinking, as far as ancient astronaut theorists are concerned, it merely confirms what they have believed all along.

77
00:08:52,000 --> 00:09:00,000
The discoveries of exoplanets over the past few years have been absolutely extraordinary.

78
00:09:01,000 --> 00:09:10,000
I remember that the first time they discovered this first exoplanet, and me and my colleagues were saying, OK, this will be the first of many.

79
00:09:11,000 --> 00:09:19,000
And now, apparently, as many as three exoplanets are being discovered on a daily basis.

80
00:09:20,000 --> 00:09:28,000
So what we've said all along, that Earth is not unique in this gigantic universe turns out to be correct.

81
00:09:29,000 --> 00:09:38,000
This raises the question that we've been bringing up, that for thousands of years there's evidence of some type of visitation from other civilizations.

82
00:09:38,000 --> 00:09:49,000
Hopefully our sciences of able to now detect exoplanets will allow us to pinpoint some of these actual home worlds where aliens have been visiting us.

83
00:09:49,000 --> 00:09:59,000
I propose that most of those planets that are in this Goldilocks zone have life very similar to ours.

84
00:10:01,000 --> 00:10:06,000
The only question is, was it them who came here thousands of years ago?

85
00:10:09,000 --> 00:10:17,000
But while a growing number of mainstream scientists do admit that intelligent life can theoretically exist elsewhere within our galaxy,

86
00:10:17,000 --> 00:10:26,000
they also argue that the distances between those planets and our own are too vast for any extraterrestrial visitation to take place.

87
00:10:27,000 --> 00:10:32,000
It is a position that puts them in direct conflict with ancient astronaut theorists,

88
00:10:32,000 --> 00:10:40,000
who contend that the keys to extraterrestrial space travel can be found in Albert Einstein's theory of relativity,

89
00:10:40,000 --> 00:10:45,000
and that a voyage to a distant star could take not centuries, but seconds.

90
00:10:48,000 --> 00:10:56,000
The Atacama Desert, Chile, August 2016

91
00:10:57,000 --> 00:11:08,000
At the La Silla Observatory, astronomers searching for exoplanets announced the detection of an Earth-like planet orbiting the closest star to our solar system, Proxima Centauri.

92
00:11:09,000 --> 00:11:18,000
They named the planet Proxima B and describe it as both Earth-like and close enough to its star to be capable of supporting life.

93
00:11:19,000 --> 00:11:24,000
One of the more interesting exoplanets we've found recently is Proxima B.

94
00:11:24,000 --> 00:11:33,000
This exoplanet is about 1.3 times the size of Earth, so scientists think that it might be rocky, which means that it could be quite similar to Earth.

95
00:11:34,000 --> 00:11:45,000
Proxima B may be habitable. We'll be able to study it in more detail with large telescopes, and in the next 10 years we may even be able to get pictures of the planet.

96
00:11:49,000 --> 00:11:59,000
Proxima B is located just over four light-years from Earth, a distance of about 25 trillion miles, despite the immense distance.

97
00:11:59,000 --> 00:12:04,000
An ambitious program is already underway to send spacecraft to study it.

98
00:12:05,000 --> 00:12:14,000
Called Breakthrough Starshot, the program began as the joint brainchild of philanthropist Eury Milner and famous cosmologist Delate Stephen Hawking.

99
00:12:15,000 --> 00:12:23,000
For the first time in human history, we can do more than just gaze at the stars. We can actually reach them.

100
00:12:24,000 --> 00:12:31,000
The goal of Breakthrough Starshot is to send tiny probes, mere centimeters thick, to the nearby planet.

101
00:12:33,000 --> 00:12:44,000
We take a computer chip, energize it with laser beams and a parachute. The laser beam inflates the parachute and shoots a chip to the nearest star.

102
00:12:45,000 --> 00:12:57,000
You deploy this and you basically just cruise. You can possibly accelerate them fairly high, 20% the speed of light, and now getting to the nearest star becomes very reasonable.

103
00:12:59,000 --> 00:13:05,000
But even traveling at such high speeds, the probes will take 20 years to complete their journey.

104
00:13:06,000 --> 00:13:14,000
Light travels at a finite speed. A very simple example of this is the sun is eight minutes away, by the way, light travels.

105
00:13:15,000 --> 00:13:18,000
And most things are millions of light-years away or thousands of light-years away.

106
00:13:19,000 --> 00:13:32,000
If we pick up a signal from another civilization, that's a big thing, but it's very distant. They may never get here. We may never meet them, indeed, because of interstellar distances.

107
00:13:33,000 --> 00:13:41,000
If, as ancient astronaut theorists believe, Earth has been visited by alien entities coming from exoplanets only now being discovered,

108
00:13:42,000 --> 00:13:49,000
such entities would have to overcome the primary obstacle to space travel, the vast distance between objects.

109
00:13:50,000 --> 00:14:00,000
You talk to many scientists and they'll say the same thing over and over again. The distances between stars is so great, impossible, that these aliens can visit us.

110
00:14:02,000 --> 00:14:13,000
Think for a moment, if they're a million years more advanced than us. Just realize that modern technology, with all our wonders, is only about 300 years old.

111
00:14:15,000 --> 00:14:26,000
In recent years, a growing number of astrophysicists have proposed that mankind's ability to unlock the mysteries of interstellar space travel might be much closer than previously thought.

112
00:14:27,000 --> 00:14:44,000
And they believe the key is by using a theoretically possible structure known as a wormhole, a bend in space-time that was first proposed by Albert Einstein, which could make travel times between stars not only shorter, but nearly instantaneous.

113
00:14:45,000 --> 00:14:58,000
From the perspective of ultimate space travel, from my point of view, wormholes are simply, you take space which can bend in our theory of general relativity, the modern theory of gravity.

114
00:14:59,000 --> 00:15:05,000
You bend it around on itself so you have two layers that are apart and you connect them with a tunnel. That tunnel is a wormhole.

115
00:15:06,000 --> 00:15:14,000
They're commonly referred to as stargates because it gives you a way to get faster than space travel across large distances.

116
00:15:15,000 --> 00:15:25,000
In theory, spacecraft that can create wormholes would be able to travel to distant exoplanets in just hours, possibly even seconds.

117
00:15:26,000 --> 00:15:38,000
If extraterrestrial civilizations far more advanced than humans do exist, could they have discovered the secrets of space travel hundreds or perhaps thousands of years ago?

118
00:15:39,000 --> 00:15:43,000
And if so, might they have even traveled here to planet Earth?

119
00:15:44,000 --> 00:15:48,000
Mount Palomar, California

120
00:15:49,000 --> 00:15:52,000
October 6, 2013

121
00:15:54,000 --> 00:16:02,000
A massive red star in the constellation Pagasis, ten times larger than our sun, explodes in a colossal supernova.

122
00:16:03,000 --> 00:16:08,000
For the first time, scientists are able to witness the death of a giant star in real time.

123
00:16:09,000 --> 00:16:24,000
But perhaps even more profound is the fact that because the dying star is 160 million light years from Earth, astronomers are actually witnessing an event that took place 160 million years ago.

124
00:16:26,000 --> 00:16:32,000
So one of the things to realize about astronomy is almost everything we are looking at is in the past.

125
00:16:33,000 --> 00:16:35,000
Because the light doesn't travel instantly.

126
00:16:36,000 --> 00:16:38,000
And a supernova is basically a star exploding.

127
00:16:39,000 --> 00:16:41,000
If it had any planets around it, those are wiped out.

128
00:16:42,000 --> 00:16:48,000
So if there was a civilization or if there was life there, what we're seeing happen now, happened very far in the past.

129
00:16:49,000 --> 00:16:56,000
The violent death of the star in Pagasis provides dramatic confirmation that the universe is both ancient and dynamic.

130
00:16:57,000 --> 00:17:09,000
But ancient astronaut theorists believe such discoveries also provide reasons why an advanced extraterrestrial civilization might need to leave its home planet in search of other worlds.

131
00:17:11,000 --> 00:17:23,000
When astronomers look out into the galaxy for dying suns, if there were beings who had an advanced civilization around this dying sun,

132
00:17:24,000 --> 00:17:31,000
they would in theory want to migrate to another solar system, to another planet that they could inhabit.

133
00:17:32,000 --> 00:17:37,000
And it's quite possible that they did that and came to our planet, in fact.

134
00:17:39,000 --> 00:17:44,000
We know that billions of years from now our own star, our sun, will go supernova.

135
00:17:45,000 --> 00:17:50,000
And we are very close now to being able to venture out or migrate to another habitable planet.

136
00:17:50,000 --> 00:17:55,000
We can extrapolate that to ancient civilizations as well, ancient star civilizations,

137
00:17:55,000 --> 00:18:02,000
who knew that their own star was ready to go supernova and they embarked on a plan of planetary migration.

138
00:18:06,000 --> 00:18:14,000
Has the story of the cosmos been in part a story of the extraterrestrial migration of various advanced exoplanet life forms?

139
00:18:15,000 --> 00:18:21,000
As far as ancient astronaut theorists are concerned, the answer is a resounding yes.

140
00:18:22,000 --> 00:18:32,000
And they claim the proof can be found by carefully examining everything from ancient carvings to the religious beliefs of ancient cultures from across the globe.

141
00:18:36,000 --> 00:18:42,000
La Silla Observatory, Chile, 2011

142
00:18:43,000 --> 00:18:50,000
Astronomers announced the discovery of a large earth-like planet orbiting a star in the constellation Orion.

143
00:18:51,000 --> 00:18:57,000
The planet is located in the Goldilocks zone and the star orbits is very similar to our own,

144
00:18:58,000 --> 00:19:02,000
making it an ideal candidate for extraterrestrial life.

145
00:19:04,000 --> 00:19:10,000
This is exciting because we want to have a stable solar system like the planet earth. That's the goal.

146
00:19:10,000 --> 00:19:17,000
As far as ancient astronaut theorists are concerned, this may be the most compelling exoplanet discovery yet,

147
00:19:17,000 --> 00:19:24,000
because throughout the world, numerous ancient cultures have told stories of otherworldly visitors coming from Orion

148
00:19:25,000 --> 00:19:29,000
and even built their most important structures in alignment with that constellation.

149
00:19:30,000 --> 00:19:36,000
All around the world, there are these ancient structures that have been built in the form of Orion.

150
00:19:37,000 --> 00:19:46,000
One example that comes to mind is the Great Pyramid of Giza, where the three pyramids are aligned according to the bell stars of Orion.

151
00:19:48,000 --> 00:19:54,000
But also in the American Southwest, there are structures that are in reference to Orion.

152
00:19:55,000 --> 00:20:02,000
Native American myths talk specifically about visitors who came here from the Orion constellation.

153
00:20:06,000 --> 00:20:24,000
The fact that Orion's constellation exists in magnificent archaeological monuments on earth indicates to me that someone at some point taught our ancestors where and how to build these structures to illustrate where they are from.

154
00:20:27,000 --> 00:20:35,000
Is it possible that the exoplanet discovered in the Orion constellation is the same place where extraterrestrial visitors to Earth came from?

155
00:20:36,000 --> 00:20:38,000
Thousands of years ago.

156
00:20:39,000 --> 00:20:44,000
For ancient astronaut theorists, such an audacious notion is a very real possibility.

157
00:20:45,000 --> 00:20:51,000
And they also insist that Orion is not the only star system for more aliens may have come.

158
00:20:52,000 --> 00:21:00,000
All over the world, we have different cultures who identify with certain star systems as their origins.

159
00:21:00,000 --> 00:21:06,000
The Quechua people of Peru, they believe that we're from the Pleiades.

160
00:21:08,000 --> 00:21:16,000
In Africa, we have the Dogon who are saying that our origin is actually with the Sirius star system.

161
00:21:17,000 --> 00:21:23,000
Various cultures have imagined they have come from specific places, the Pleiades or Sirius.

162
00:21:23,000 --> 00:21:34,000
Well, that would be a planet near the star system, suggesting that at least in mythology there are planets there that could be inhabited by creatures like us.

163
00:21:35,000 --> 00:21:51,000
While many ancient cultures pointed to distant star systems as the homes of their gods, ancient astronaut theorists suggest that one of the oldest human civilizations, the Sumerians, left records of other worldly beings that came from a planet right in our own solar system.

164
00:21:51,000 --> 00:21:56,000
A planet that until very recently was thought not to exist.

165
00:22:00,000 --> 00:22:04,000
New York City, 1976.

166
00:22:05,000 --> 00:22:17,000
Author Zechariah Sitchin publishes his landmark book, The Twelfth Planet, the first of over a dozen books based upon Sitchin's translations of ancient Sumerian texts.

167
00:22:17,000 --> 00:22:24,000
The Twelfth Planet ultimately reshapes the way millions of people view the history of life on Earth.

168
00:22:25,000 --> 00:22:33,000
In it, Sitchin claims that ancient Sumerians wrote about an extraterrestrial race that once visited Earth, the Anunnaki.

169
00:22:34,000 --> 00:22:48,000
The term Anunnaki is essentially interchangeable with extraterrestrial, because the word Anunnaki itself means those who from the heavens came.

170
00:22:51,000 --> 00:22:53,000
There's a whole pantheon of Anunnaki, basically.

171
00:22:53,000 --> 00:23:00,000
There was Anu, who is essentially the king of all the Anunnaki, and then his two sons, Enel and Anki.

172
00:23:01,000 --> 00:23:08,000
When we look in a lot of the Sumerian tablets, they seem to have come from a much larger planet, a reddish glowing planet.

173
00:23:10,000 --> 00:23:14,000
One of the great questions about the Anunnaki is, where did they come from?

174
00:23:14,000 --> 00:23:25,000
Well, Zechariah went back into the ancient texts and began to build a theory that the Anunnaki came from an as-yet undiscovered twelfth planet in our solar system that he called Nibiru.

175
00:23:28,000 --> 00:23:37,000
Nibiru is described as a much larger planet than Earth, and it has a very elliptical orbit, more like a large egg-shaped orbit.

176
00:23:37,000 --> 00:23:46,000
The kicker here is that it goes once around the sun every 3600 years, so a solar year for them is 3600 of our years.

177
00:23:48,000 --> 00:23:58,000
Zechariah believed that there was a time during this 3600 year orbit when this planet was actually relatively close to the Earth.

178
00:23:58,000 --> 00:24:11,000
And Zechariah theorized that the Anunnaki would then fire their rockets and then they would come here to Earth, and that this was how they were interacting with humans.

179
00:24:13,000 --> 00:24:18,000
For decades, astronomers claimed that no such planet could exist in our solar system.

180
00:24:19,000 --> 00:24:28,000
But in 2016, Caltech astronomers, Constantine Boutigan and Mike Brown, made a discovery that could prove this theory wrong.

181
00:24:29,000 --> 00:24:40,000
Boutigan and Brown were using an interesting method of looking for other planets in the solar system, namely, they were looking at dwarf planets and distant Kuiper Belt objects to see how they move.

182
00:24:41,000 --> 00:24:53,000
If they exhibit any strange behavior, astronomers can use that to theorize new planets, and what they found was a theoretical planet-sized mass orbiting in a hugely elliptical orbit around the sun.

183
00:24:54,000 --> 00:25:05,000
Astronomers have often suspected, because of certain gravitational anomalies and things, that there is still some other planet far out in our solar system.

184
00:25:05,000 --> 00:25:21,000
Beyond Pluto, astronomers call this other planet Planet X, and it could be a very large planet. Astronomers cannot see it, but I would suspect that astronomers will eventually discover it and prove that it exists.

185
00:25:23,000 --> 00:25:32,000
Boutigan and Brown estimate that Planet X has a highly elliptical orbit and takes it thousands of years to make a single trip around our sun.

186
00:25:33,000 --> 00:25:42,000
This matches exactly what Zechariah's Sitchin found in his translation of the ancient Sumerian tablets concerning an extra planet in our solar system.

187
00:25:43,000 --> 00:25:56,000
The thing about it is that if we discover Planet X, then we will also discover the Anunnaki. So they're absolutely entwined, the idea of the Anunnaki and the discovery of Planet X will prove one another.

188
00:25:57,000 --> 00:26:09,000
Could extraterrestrials have come to Earth from a planet within our own solar system? And if Earth has, in fact, played host to alien visitors from multiple worlds, what brought them here?

189
00:26:10,000 --> 00:26:17,000
According to the ancient Sumerian tablets, the Anunnaki valued one thing above all else. Gold.

190
00:26:18,000 --> 00:26:37,000
Los Angeles, California, June 2019. The Trans-Astronautic Corporation announces a partnership with NASA to develop a new venture in space, Asteroid Mining.

191
00:26:38,000 --> 00:26:55,000
We incorporated Trans-Aster in 2015 when we saw that SpaceX and Elon Musk and Blue Origin, Jeff Bezos and other entrepreneurs were developing low-cost, really effective ways to get into orbit.

192
00:26:56,000 --> 00:27:06,000
Once we have rockets that can get into orbit inexpensively, then it makes sense to start building real industries in space. And one of the first industries is Asteroid Mining.

193
00:27:07,000 --> 00:27:20,000
Precious metals that we really value on the Earth. Things like gold and platinum. They're called precious metals because they're not around much. The question is, where are they? And the answer is, asteroids.

194
00:27:21,000 --> 00:27:35,000
Metals like gold, copper and zinc have been mined on Earth for thousands of years and are vital to civilization. But their supply is finite, in part because they are not native to this planet.

195
00:27:36,000 --> 00:27:53,000
When the Earth was originally being formed, it was molten. And a lot of the precious metals were drawn towards the center of the Earth. And through this molten process, all the heavy elements went down to the core of the Earth where we can't get access to them.

196
00:27:54,000 --> 00:27:59,000
Then the Earth started to cool and form a cool crust which was made of lighter materials.

197
00:28:00,000 --> 00:28:21,000
It is widely accepted that without access to metals, both technology and civilization would not have been possible. But luckily for mankind, some 3.8 billion years ago, it is estimated that trillions of asteroids crashed into the Earth and deposited a layer of heavy metals into the planet's now hardened crust.

198
00:28:24,000 --> 00:28:34,000
These elements weren't actually from Earth originally. All of these elements came to Earth via comets and asteroids that impacted our planet long ago and early in its history.

199
00:28:37,000 --> 00:28:41,000
So all the precious metals that we mine on the Earth actually came from the asteroids.

200
00:28:42,000 --> 00:28:55,000
The bombardment of asteroids seated Earth's crust with enough metals to make possible the Bronze Age, the Iron Age and today's technological civilization.

201
00:28:56,000 --> 00:29:03,000
But many metals, including rare Earth elements needed for high technology, are in increasingly short supply.

202
00:29:04,000 --> 00:29:10,000
Because of this, many experts believe the asteroid belt may once again come to the rescue.

203
00:29:11,000 --> 00:29:20,000
You get a typical asteroid of 200 meters in diameter. It will have more of those rare Earth elements that have been mined on Earth in all of human history.

204
00:29:21,000 --> 00:29:34,000
Of the more than 6,000 asteroids in NASA's database, it is estimated that even just the 10 easiest to reach and mine would yield an astonishing $1.5 trillion in resources.

205
00:29:35,000 --> 00:29:42,000
The asteroid belt could provide for the needs of our civilization for many centuries, maybe thousands of years into the future.

206
00:29:43,000 --> 00:29:56,000
The natural thing to do is to build spacecraft, to go out to the asteroids, to mine them, to make goods out of the asteroids.

207
00:29:56,000 --> 00:30:06,000
And we presume that other intelligences, if there are other intelligences, would think the same way we would and so anything that seems to make sense to us could make sense to others.

208
00:30:07,000 --> 00:30:20,000
If other intelligent life forms exist on nearby exoplanets, might they too be aware of the vast resources that exist in the asteroid belt and also on planet Earth?

209
00:30:21,000 --> 00:30:34,000
Ancient astronaut theorists say yes and suggest that Earth is rich in another commodity that would be of great value to any advanced civilization looking to mine for precious metals.

210
00:30:34,000 --> 00:30:36,000
Liquid water.

211
00:30:37,000 --> 00:30:46,000
If aliens wanted to mine the asteroid belt, they'd need a base somewhere to regroup and refuel.

212
00:30:46,000 --> 00:30:50,000
As it happens, there's one pretty close and it's called planet Earth.

213
00:30:51,000 --> 00:30:58,000
White aliens coming here might well be because we're mostly water on planet Earth.

214
00:30:58,000 --> 00:31:08,000
They stop here because they could break down water into hydrogen and oxygen as fuel.

215
00:31:09,000 --> 00:31:18,000
So if you have a craft that somehow uses the hydrogen power, you have all the hydrogen you ever need.

216
00:31:18,000 --> 00:31:24,000
It well could be that this is a way station for extraterrestrials.

217
00:31:25,000 --> 00:31:39,000
Is it possible that extraterrestrial civilizations have come to Earth not only as refugees from planets orbiting dying stars, but also to mine precious metals or abundant natural resources like water?

218
00:31:39,000 --> 00:31:48,000
And if so, would that indicate that these Earth visitors might be physically very similar to ourselves?

219
00:31:55,000 --> 00:32:01,000
La Silla Observatory, Chile, 2009

220
00:32:01,000 --> 00:32:08,000
Astronomers identify a potentially habitable planet orbiting the star Liza-667C.

221
00:32:08,000 --> 00:32:14,000
It's a large Earth-like planet located firmly in the Goldilocks zone.

222
00:32:14,000 --> 00:32:22,000
While evidence of life has yet to be discovered, scientists are able to speculate as to how life on this planet would evolve.

223
00:32:22,000 --> 00:32:33,000
When we imagine life on other planets, we have to imagine that the environment on those planets will determine what the creature may look like.

224
00:32:35,000 --> 00:32:42,000
In considering planets larger than Earth, the increased gravity will likely result in shorter, complex life forms.

225
00:32:42,000 --> 00:32:47,000
This results in a more stable life form and protects against falls.

226
00:32:47,000 --> 00:32:52,000
So life forms on larger planets would likely be smaller than those on smaller planets.

227
00:32:52,000 --> 00:32:58,000
Like Earth, a major evolutionary force on the planet is the strength of its sun.

228
00:32:59,000 --> 00:33:07,000
Gleiza-667C is a red dwarf star, an M star, that's about 1.4% as bright as our sun.

229
00:33:07,000 --> 00:33:13,000
Because M dwarf stars are much smaller than our sun, they're much cooler and they give off a lot less light.

230
00:33:13,000 --> 00:33:20,000
Because the star gives out such low light compared to our sun, any life on those planets would look much different.

231
00:33:21,000 --> 00:33:26,000
Let's assume for the sake of argument that there is life on Gleiza-667C.

232
00:33:26,000 --> 00:33:30,000
Such life would be living in kind of eternal darkness.

233
00:33:30,000 --> 00:33:42,000
In order for life forms on a planet like that to see they'd be like owls on planet Earth, they would have very, very large eyes to capture as much light as possible.

234
00:33:43,000 --> 00:33:53,000
They are going to develop eyes that are perhaps more like insect's eyes, where you're seeing different light spectrums and heat signatures.

235
00:33:53,000 --> 00:33:57,000
Something completely different than the way we see.

236
00:33:58,000 --> 00:34:07,000
For ancient astronaut theorists, these descriptions share a curious similarity to accounts reported by alleged alien abductees.

237
00:34:08,000 --> 00:34:15,000
Alien abductees give very consistent accounts of some of the types of aliens they see.

238
00:34:16,000 --> 00:34:24,000
The most consistent account is four feet short, grey, big-headed, big-eyed aliens.

239
00:34:24,000 --> 00:34:31,000
And this would fit what we might expect with gravity so intense that you couldn't grow to six feet.

240
00:34:32,000 --> 00:34:36,000
Short grey aliens with large black eyes?

241
00:34:36,000 --> 00:34:46,000
Is it possible that the habitable planet orbiting Gleiza-667C is the homeworld of the beings known in the UFO community as the grays?

242
00:34:48,000 --> 00:34:58,000
As far as ancient astronaut theorists are concerned, the planet orbiting Gleiza-667C is just one of a number of recently discovered worlds

243
00:34:58,000 --> 00:35:06,000
that could represent places of origin for extraterrestrials encountered both in modern times and in the distant past.

244
00:35:08,000 --> 00:35:14,000
Mountain View, California, April 2013.

245
00:35:15,000 --> 00:35:25,000
NASA scientists at the Ames Research Center announced that the Kepler Space Telescope has discovered two new exoplanets that seem highly promising for life.

246
00:35:25,000 --> 00:35:35,000
Named Kepler-62E and 62F, they are so-called water worlds, planets covered by an all-encompassing global ocean.

247
00:35:36,000 --> 00:35:42,000
The planets 62E and F are very exciting because they are ocean-covered planets and in the habitable zone.

248
00:35:42,000 --> 00:35:48,000
So if you're an ocean-covered planet, it increases the chance that there's actually life on that planet.

249
00:35:49,000 --> 00:35:59,000
If there is a water world with an atmosphere, with water, the creatures that may inhabit there are water-born creatures.

250
00:35:59,000 --> 00:36:06,000
They wouldn't necessarily look like human beings standing up on two legs and two arms. They might look more like mermaids.

251
00:36:07,000 --> 00:36:15,000
Ancient astronaut theorists point out that many early civilizations reported sky visitors with amphibious fish-like characteristics.

252
00:36:16,000 --> 00:36:25,000
Considered to be gods, they were seen in China, Sub-Saharan Africa, Central America and Egypt just to name a few.

253
00:36:26,000 --> 00:36:33,000
These amphibian beings were said to interact with humans by day and retreat to rivers or lakes at night.

254
00:36:34,000 --> 00:36:40,000
Could such entities have come from so-called water worlds like Kepler-62E and F?

255
00:36:41,000 --> 00:36:49,000
Creatures like that, if they existed, would evolve on water worlds, planets with a global ocean.

256
00:36:50,000 --> 00:36:57,000
And it just so happens that in the ongoing search for exoplanets, many such worlds are being discovered.

257
00:36:58,000 --> 00:37:07,000
These half-human, half-fish-type gods that are like us but are still aquatic and are coming from these water planets.

258
00:37:08,000 --> 00:37:20,000
Exotraterrestrials may be very attracted to planet Earth because the oceans are huge and vast, so aquatic extraterrestrials could find a very happy home here on planet Earth.

259
00:37:20,000 --> 00:37:33,000
So when we encounter alien lifeforms on a space, are they going to look like us? No. They could look completely different from us and have a different pathway to intelligence.

260
00:37:34,000 --> 00:37:43,000
In their search for habitable exoplanets, could mainstream scientists be discovering the home worlds of extraterrestrial visitors to Earth?

261
00:37:44,000 --> 00:37:48,000
For ancient astronaut theorists, the answer is a resounding yes.

262
00:37:49,000 --> 00:38:01,000
And they suggest that the search for life is about to be revolutionized once again, as NASA prepares to launch an extraordinary new technology into space.

263
00:38:06,000 --> 00:38:10,000
Geneva, Switzerland, October 8th, 2019

264
00:38:11,000 --> 00:38:21,000
Astronomers Michel Mayor and Didier Cuolos are awarded the Nobel Prize in Physics for discovering the first exoplanet in 1992.

265
00:38:22,000 --> 00:38:30,000
In the years since, more than 4,000 have been examined and categorized, and more are being found every day.

266
00:38:31,000 --> 00:38:39,000
Let's do a science experiment tonight. Go outside, look up and see all the thousands of stars you see.

267
00:38:40,000 --> 00:38:49,000
Every single one, on average, has a planet going around them, and about 1 in 20 has an Earth-like planet.

268
00:38:50,000 --> 00:38:57,000
And so when you look at the stars tonight, realize that somebody could be looking back at you from outer space.

269
00:39:00,000 --> 00:39:13,000
In 2021, NASA will launch the James Webb Space Telescope, a satellite that can do something once thought impossible, take detailed color images of an exoplanet.

270
00:39:15,000 --> 00:39:21,000
The James Webb Space Telescope is a different type of telescope than we've had in space before.

271
00:39:21,000 --> 00:39:32,000
It will give us the ability to look at the reflected light from exoplanets in the infrared part of the spectrum and to search for the potential for biology being present.

272
00:39:34,000 --> 00:39:42,000
But when we look upon the images of other worlds, and possibly even the beings that inhabit them, what will we find?

273
00:39:43,000 --> 00:39:58,000
I think that what's really lying in store for humanity now is that we will prove that there are these exoplanets out there, that they have life, and quite possibly intelligent life, capable of coming to our solar system.

274
00:39:59,000 --> 00:40:08,000
This will cause a sea change all over the world, within scientific communities and within the religious communities too.

275
00:40:08,000 --> 00:40:17,000
If astronomers discover exoplanets with intelligent alien life forms, will they appear eerily familiar?

276
00:40:18,000 --> 00:40:23,000
Could they find amphibious humanoid beings like the gods depicted in ancient times?

277
00:40:24,000 --> 00:40:28,000
Small, gray aliens like those reported by alleged abductees?

278
00:40:29,000 --> 00:40:38,000
And is it possible that some visitors perhaps coming from worlds very similar to Earth might look remarkably like us?

279
00:40:39,000 --> 00:40:54,000
Within established ancient astronaut theory, it's generally thought that these extraterrestrial beings coming from outside of our solar system were interacting with our society and they were manipulating our DNA.

280
00:40:54,000 --> 00:41:00,000
And in a sense, creating people on this planet, us, who look like them and are similar to them.

281
00:41:01,000 --> 00:41:07,000
As we discover more and more exoplanets, the implications for humanity are enormous.

282
00:41:08,000 --> 00:41:15,000
I think it's very possible that we're on the verge of discovering our home planet, the place of our origins.

283
00:41:16,000 --> 00:41:23,000
The big revelation will not be do they look like us, but we look like them, because we are their offspring.

284
00:41:24,000 --> 00:41:37,000
As scientists continue their search for habitable worlds, are we on the verge of discovering not only alien life, but the very extraterrestrials that came to Earth centuries ago?

285
00:41:38,000 --> 00:41:48,000
And will we find that the strange gods depicted by our ancestors as mythological creations were very real flesh and blood entities, not so different from ourselves?

286
00:41:48,000 --> 00:42:04,000
Perhaps one day soon, we will look at the satellite image of a distant exoplanet and see not only mankind's future home, but one that could have once been inhabited by our ancient alien ancestors.
