1 00:00:00,000 --> 00:00:10,040 A temple of the dead in the Yucatan, an underground city 2 00:00:10,040 --> 00:00:14,880 in Turkey, and a South American cave 3 00:00:14,880 --> 00:00:17,840 said to contain a treasure from beyond the stars. 4 00:00:22,760 --> 00:00:27,120 For centuries, people have told tales of caves and tunnels 5 00:00:27,120 --> 00:00:29,520 deep inside the Earth. 6 00:00:29,560 --> 00:00:35,960 Subterranean passageways that lead to lands of gods and monsters. 7 00:00:35,960 --> 00:00:40,880 But is there a surprising truth behind these legends? 8 00:00:40,880 --> 00:00:43,640 I have stood in front of drawings on the rocks 9 00:00:43,640 --> 00:00:47,040 and wondered, am I looking at the extraterrestrial 10 00:00:47,040 --> 00:00:48,960 biological entity? 11 00:00:48,960 --> 00:00:54,600 Could there really be mysterious places far beneath our feet? 12 00:00:54,600 --> 00:00:59,200 Places whose origins might not be of this Earth? 13 00:00:59,200 --> 00:01:01,840 There were certain aspects of the caves 14 00:01:01,840 --> 00:01:05,800 for which geology could not provide an answer. 15 00:01:05,800 --> 00:01:08,600 Millions of people around the world 16 00:01:08,600 --> 00:01:10,920 believe we have been visited in the past 17 00:01:10,920 --> 00:01:14,080 by extraterrestrial beings. 18 00:01:14,080 --> 00:01:16,880 What if it were true? 19 00:01:16,880 --> 00:01:21,880 Did ancient aliens really help to shape our history? 20 00:01:21,880 --> 00:01:25,880 And if so, should we be looking for proof of their existence 21 00:01:25,880 --> 00:01:29,200 not in the heavens above, but in mysterious worlds 22 00:01:29,200 --> 00:01:30,720 deep beneath the surface? 23 00:02:01,720 --> 00:02:04,720 Bordered on the north by the Black Sea 24 00:02:04,720 --> 00:02:07,720 and by the Taurus Mountains to the south, 25 00:02:07,720 --> 00:02:11,720 lies Cappadocia in central Turkey. 26 00:02:11,720 --> 00:02:15,720 Here, wind and water have sculpted strange shapes 27 00:02:15,720 --> 00:02:18,720 out of the soft volcanic rock, 28 00:02:18,720 --> 00:02:21,720 rock which ancient peoples once turned 29 00:02:21,720 --> 00:02:24,720 into small primitive dwellings. 30 00:02:24,720 --> 00:02:28,720 In more recent years, the site has seen the construction 31 00:02:29,720 --> 00:02:32,720 of more modern structures. 32 00:02:34,720 --> 00:02:37,720 But in 1963, a simple home renovation 33 00:02:37,720 --> 00:02:42,720 in the town of Derinkuyu led to an extraordinary discovery 34 00:02:42,720 --> 00:02:45,720 when a cave wall was opened, 35 00:02:45,720 --> 00:02:48,720 revealing a passageway to an underground city 36 00:02:48,720 --> 00:02:54,720 thousands of years old and more than 280 feet deep. 37 00:02:54,720 --> 00:02:57,720 I've been there on multiple occasions 38 00:02:57,720 --> 00:03:01,720 and it's incredible because there's 13 stories 39 00:03:01,720 --> 00:03:05,720 that go deep into the ground with ventilation shafts 40 00:03:05,720 --> 00:03:09,720 and 15,000 little shafts that bring air 41 00:03:09,720 --> 00:03:12,720 to even the deepest of levels. 42 00:03:14,720 --> 00:03:18,720 Incredibly, the number of rock rooms that were found 43 00:03:18,720 --> 00:03:22,720 could hold over 20,000 men, women and children. 44 00:03:22,720 --> 00:03:26,720 There was even evidence of religious centers. 45 00:03:26,720 --> 00:03:32,720 Store rooms, wine presses and stables for livestock. 46 00:03:32,720 --> 00:03:35,720 Oh, Derinkuyu would have been a massive undertaking 47 00:03:35,720 --> 00:03:39,720 for anyone, even in modern times, with modern equipment. 48 00:03:39,720 --> 00:03:44,720 But in those days, it would have been stupendous, 49 00:03:44,720 --> 00:03:47,720 equal to the pyramids. 50 00:03:48,720 --> 00:03:52,720 At Derinkuyu, because of the softness of the stone, 51 00:03:52,720 --> 00:03:57,720 you had to be very careful that you provided enough pillar strength 52 00:03:57,720 --> 00:04:01,720 to support the floors above, otherwise you'd have catastrophic cave-ins. 53 00:04:01,720 --> 00:04:05,720 Surprisingly, there's no evidence of any catastrophic cave-ins, 54 00:04:05,720 --> 00:04:10,720 so they were apparently extremely clever and knew their material. 55 00:04:10,720 --> 00:04:12,720 We're talking deep antiquity. 56 00:04:12,720 --> 00:04:16,720 It is mind-boggling to understand how they could have done this. 57 00:04:16,720 --> 00:04:20,720 Perhaps they had help from some other civilization. 58 00:04:20,720 --> 00:04:24,720 But just who built this massive underground city? 59 00:04:24,720 --> 00:04:29,720 And what mysterious force drove them to live underground? 60 00:04:29,720 --> 00:04:31,720 Why? 61 00:04:31,720 --> 00:04:37,720 What people want to live deep underground in these weird caverns like that, 62 00:04:37,720 --> 00:04:40,720 it seems kind of scary, really. 63 00:04:42,720 --> 00:04:45,720 According to many archaeologists and scholars, 64 00:04:45,720 --> 00:04:51,720 Derinkuyu was most likely intended to serve as a temporary shelter from invasion, 65 00:04:51,720 --> 00:04:55,720 built around 800 BC by the Phrygians, 66 00:04:55,720 --> 00:04:59,720 a Bronze Age people related to the Trojans. 67 00:04:59,720 --> 00:05:02,720 Others believe it was built by the Hidites, 68 00:05:02,720 --> 00:05:07,720 a warrior people mentioned in the Bible, who flourished hundreds of years earlier. 69 00:05:07,720 --> 00:05:11,720 But could the underground city be even older? 70 00:05:11,720 --> 00:05:15,720 According to ancient astronaut theorists, it is. 71 00:05:15,720 --> 00:05:19,720 Perhaps by many thousands of years. 72 00:05:19,720 --> 00:05:24,720 The Cappadocia region of Turkey was part of the Zoroastrian Empire, 73 00:05:24,720 --> 00:05:26,720 which was Persian in nature. 74 00:05:26,720 --> 00:05:31,720 And it's one of the oldest religious traditions on the face of the earth. 75 00:05:33,720 --> 00:05:40,720 The Zoroastrian religion, an ancient faith based on opposing forces of good and evil, 76 00:05:40,720 --> 00:05:46,720 is widely believed to have influenced both Hinduism and Judeo-Christianity. 77 00:05:46,720 --> 00:05:50,720 Founded sometime before the 6th century BC, 78 00:05:50,720 --> 00:05:54,720 its chief god is the creator, Ahuru Mazda. 79 00:05:54,720 --> 00:06:00,720 And in the second chapter of the Zoroastrian sacred text, the Vendidad, 80 00:06:00,720 --> 00:06:06,720 Ahuru Mazda saves mankind from a worldwide environmental disaster, 81 00:06:06,720 --> 00:06:10,720 much like the story of Noah in the Hebrew Testament. 82 00:06:10,720 --> 00:06:16,720 The great prophet Yema, he was instructed to build a kind of underground refuge 83 00:06:16,720 --> 00:06:21,720 similar to Durankuyu by the sky god, Ahuru Mazda. 84 00:06:24,720 --> 00:06:26,720 According to the sacred texts, 85 00:06:26,720 --> 00:06:32,720 Yema built a multi-level underground city to protect a select group of people and animals. 86 00:06:32,720 --> 00:06:36,720 Not from a flood, but from a global ice age. 87 00:06:36,720 --> 00:06:40,720 The Vendidad calls this the Evil Winters. 88 00:06:42,720 --> 00:06:45,720 According to many mainstream climatologists, 89 00:06:45,720 --> 00:06:52,720 the last ice age peaked around 18,000 years ago and ended around 10,000 BC. 90 00:06:52,720 --> 00:06:59,720 Is it possible that Durankuyu was built as a refuge from a devastating global winter? 91 00:07:03,720 --> 00:07:06,720 Since you cannot carbon-date stone, 92 00:07:06,720 --> 00:07:10,720 it's anybody's guess how old Durankuyu really is. 93 00:07:10,720 --> 00:07:16,720 And my question is, if we have a Zoroastrian story that's very similar, 94 00:07:16,720 --> 00:07:26,720 could it be that both that place and Durankuyu are much, much older than what we've believed so far? 95 00:07:26,720 --> 00:07:33,720 But if Durankuyu is, in fact, the underground city that Ahuru Mazda told his followers to build, 96 00:07:33,720 --> 00:07:37,720 could there be a stunning truth behind the legend? 97 00:07:37,720 --> 00:07:43,720 If so, who or what was the god Ahuru Mazda? 98 00:07:43,720 --> 00:07:50,720 Ahuru Mazda does appear to be responsible for the management of whatever is happening here on Earth. 99 00:07:51,720 --> 00:07:58,720 There are various ways to read this, one of which is that it does represent some sort of higher, universal form of consciousness, 100 00:07:58,720 --> 00:08:03,720 but another is that it would represent an overseeing extraterrestrial intelligence. 101 00:08:07,720 --> 00:08:13,720 Several sacred texts from antiquity speak of knowledge given to mankind from extraterrestrials, 102 00:08:13,720 --> 00:08:16,720 but also known as gods from antiquity. 103 00:08:17,720 --> 00:08:23,720 Could the sky god Ahuru Mazda really have been an advanced being from another world? 104 00:08:23,720 --> 00:08:33,720 If so, did he provide the technology needed for his followers to build this complex labyrinth as protection from environmental disaster? 105 00:08:34,720 --> 00:08:39,720 Or is there possibly a more ominous reason for Durankuyu's existence? 106 00:08:40,720 --> 00:08:46,720 Some say a clue lies in the underground city's unusual security system. 107 00:08:46,720 --> 00:08:54,720 One thousand pound doors unrollers that allow them to be moved by a single person, but only from one side. 108 00:08:54,720 --> 00:08:58,720 The Durankuyu doors are very cleverly constructed. 109 00:08:58,720 --> 00:09:02,720 You can basically only open it and leverage it from the inside. 110 00:09:02,720 --> 00:09:09,720 So obviously whoever inhabited Durankuyu was hiding from someone or something. 111 00:09:12,720 --> 00:09:19,720 According to the ancient Zoroastrian texts, Ahuru Mazda soared through the sky in a divine chariot 112 00:09:19,720 --> 00:09:26,720 and waged war against his eternal enemy, Angra Mainyu, the demon of destruction. 113 00:09:27,720 --> 00:09:33,720 But could this really be, as many ancient astronaut theorists believe, 114 00:09:33,720 --> 00:09:40,720 a depiction of two extraterrestrial forces battling over control of the Earth and its resources? 115 00:09:41,720 --> 00:09:48,720 The aerial enemies were extraterrestrials because they were the ones who had the capability of flight. 116 00:09:49,720 --> 00:09:59,720 They had access to those types of machines that we can read about in every single ancient culture around the world. 117 00:10:00,720 --> 00:10:08,720 When you look at the Zoroastrian tradition, you also see clear evidence that there was some sort of extraterrestrial battle going on between warring factions. 118 00:10:09,720 --> 00:10:23,720 Therefore it is certainly possible that the original caves may have been used as shelters against possible aerial bombardment from extraterrestrials that were warring with each other during that time. 119 00:10:24,720 --> 00:10:35,720 Durankuyu was built out of fear of an aerial enemy because if something flies over you very, very fast, you can't see the ventilation shafts. 120 00:10:36,720 --> 00:10:41,720 Some suggest 30,000 people used to live underground at Durankuyu. 121 00:10:45,720 --> 00:10:56,720 During recorded history, many different peoples did, in fact, hide in the underground city of Durankuyu to escape everything from desert raiders to Roman legions. 122 00:10:57,720 --> 00:11:05,720 But some experts wonder whether such conventional attacks can really explain why Durankuyu was built in the first place. 123 00:11:06,720 --> 00:11:17,720 If it were an enemy that was on a horseback, it would be easy for them to just smother everyone inside by just closing all the ventilation shafts. 124 00:11:18,720 --> 00:11:26,720 We had the phrase in the Defense Department studies that I participated in that a cave is a grave to a well-prepared adversary. 125 00:11:26,720 --> 00:11:30,720 Once you find it, it is highly vulnerable. 126 00:11:31,720 --> 00:11:40,720 But did the people of Durankuyu really go underground to avoid becoming casualties in an extraterrestrial battle in the skies? 127 00:11:41,720 --> 00:11:46,720 And if so, might there be other such cities from the distant past? 128 00:11:47,720 --> 00:11:51,720 According to ancient astronaut theorists, there are. 129 00:11:51,720 --> 00:11:59,720 And they can be found much nearer to home, deep in the caves of the American Southwest. 130 00:12:07,720 --> 00:12:15,720 The majestic maces and rugged mountains of the American Southwest are home to many native peoples, 131 00:12:15,720 --> 00:12:25,720 including the Navajo, Zuni, Pueblo, Hopi and Apache. 132 00:12:26,720 --> 00:12:33,720 These tribes have many different beliefs, but their creation myths all share something quite remarkable. 133 00:12:35,720 --> 00:12:42,720 We were talking about our origin, and you know, you hear the stories about us coming down from Alaska to the Bering Strait. 134 00:12:42,720 --> 00:12:45,720 But what we believe is we came out from the ground. 135 00:12:47,720 --> 00:13:02,720 The Apaches and other Pueblo Indians, such as the Zunis and the Hopi Indians, all have this legend that they emerged from some underground world into today's world. 136 00:13:03,720 --> 00:13:12,720 In some legends, the Southwestern peoples went back underground for safety. 137 00:13:15,720 --> 00:13:29,720 The Hopi of Arizona say their ancestors escaped a deadly storm of falling stars with the help of the snake people, who took them to shelters deep in the earth. 138 00:13:32,720 --> 00:13:40,720 Another Hopi legend speaks of the ant people, who protected them from storms of fire and ice. 139 00:13:42,720 --> 00:13:57,720 The Hopi Indians survived cataclysms by living in this underground world with the ant people for a certain period of time, and then eventually they emerged from the underground world back into the surface world. 140 00:13:58,720 --> 00:14:13,720 Ant people. Snake people. Could these stories be based on ancestral tales of people actually living underground, possibly during the last Ice Age? 141 00:14:14,720 --> 00:14:23,720 Or could the ancestors of today's Southwestern tribes have taken refuge in subsurface dwellings similar to the underground city of Derinkuyu in Turkey? 142 00:14:24,720 --> 00:14:36,720 If so, over the centuries, might they have developed physical traits like large eyes and fingers that made them more closely resemble actual earth-dwelling creatures? 143 00:14:36,720 --> 00:14:57,720 The shamans and the elders of Native Americans, they will tell you that before these people were able to emerge out of planet earth, they were brought here by the star people, the star gods, which arrived from outer space. 144 00:14:58,720 --> 00:15:18,720 I have stood in front of what are called the ant people and some of the very strange large eye drawings on the rocks and wondered, am I looking at Native American interpretation of what today is called the extraterrestrial biological entity? 145 00:15:18,720 --> 00:15:37,720 If extraterrestrials were here in the remote past, there are multiple species out there, is it possible that they might have looked lizard-like and ant-like? And the answer is yes. 146 00:15:38,720 --> 00:15:53,720 Is it possible that these underground creatures of Native American legend were actually alien visitors? If so, could some of them still be living beneath the surface of the Southwestern desert? 147 00:15:54,720 --> 00:16:19,720 For decades, stories of encounters with UFOs and alien beings have been told among the people of New Mexico's Hikariya Apache Reservation. Some of the aliens in these stories bear a strange resemblance to the ancient tales of the ant-like and snake-like beings from the Hopi legends. 148 00:16:20,720 --> 00:16:24,720 There is things up here that no one can explain. 149 00:16:25,720 --> 00:16:37,720 The Hikariya Apache Reservation is located next to the small town of Dulce, nestled in the shadow of the over 9,000-foot-high Archioleta Mesa. 150 00:16:37,720 --> 00:16:47,720 It is from this Mesa and mountain that people claim they have seen UFOs flying out of the mountain. 151 00:17:08,720 --> 00:17:17,720 Could the native tales of spaceships and strange creatures be true? Some UFO researchers and conspiracy theorists believe that these eyewitness accounts are not only true, but also true. 152 00:17:18,720 --> 00:17:21,720 The amount of military that they have seen is one in five. 153 00:17:25,720 --> 00:17:44,720 Could the native tales of spaceships and strange creatures be true? Some UFO researchers and conspiracy theorists believe that these eyewitness accounts are not only true, but are evidence of a secret collaboration between underground aliens and the U.S. military. 154 00:17:45,720 --> 00:18:00,720 The amount of military traffic over Dulce, the unmarked helicopters, the black helicopters, the heavy-duty Chinooks, all these helicopters spend a lot more time in Dulce than they should if nothing were going on here. 155 00:18:02,720 --> 00:18:10,720 Among the stories that we've heard from the Hikariya Apache is that they discovered vents actually right here on the Mesa. 156 00:18:15,720 --> 00:18:26,720 A while back when my brother was still alive, we used to come up here in the back and he showed us a shaft and that thing was bigger than me, but we walked in and I didn't want to go any further. 157 00:18:26,720 --> 00:18:55,720 The vents were here maybe 25 years ago. You'd hear strange noises, groans, sighs, human groans. And this led a lot of credence to stories that human beings were being vivisected, experimented on, and thus the legend of strange creatures and strange noises coming out of this Mesa grew and expanded. 158 00:18:57,720 --> 00:19:20,720 Aliens living underground. Strange secret government cover-ups. Could Native American legends of underground beings help unearth the truth behind these incredible stories? Some think the answer might be found deep beneath the surface of North America. 159 00:19:21,720 --> 00:19:34,720 But others believe the truth lies hidden in a mysterious cave, thousands of miles to the South, a cave that hides proof of alien visitors who journeyed beyond the stars. 160 00:19:35,720 --> 00:19:54,720 South America. The Andes mountain range in Ecuador. For thousands of years, this rainforest high on the eastern slopes has been the land of the schwar. 161 00:19:55,720 --> 00:20:04,720 Headhunters who are fiercely protective of their homeland and its secrets. 162 00:20:04,720 --> 00:20:19,720 And of all the schwar's secrets, perhaps none has been so carefully guarded as the location and entrance of the cave of Tios. But why? 163 00:20:20,720 --> 00:20:34,720 Perhaps the answer can be found in the story of an Italian Catholic missionary named Father Crespie, who lived in the region in the middle of the last century. 164 00:20:34,720 --> 00:20:45,720 Father Paolo Carlo Crespie. He was loved by the Indians. He helped them without asking for money, and the Indians made them some presents. 165 00:20:46,720 --> 00:20:55,720 But what was unique about the presents or gifts given to Father Crespie was that they often took the form of elaborately carved artifacts. 166 00:20:55,720 --> 00:21:08,720 Some made of gold or other precious metals. Often these objects featured elaborate carvings and symbols, not known to be associated with the schwar culture. 167 00:21:09,720 --> 00:21:30,720 In his 1973 book, Gold of the Gods, ancient astronaut theorist Eric Von Daniken wrote of Father Crespie's incredible collection, which he believed to come from the cave of Tios, and which were, in his opinion, treasures from an unknown and highly advanced culture. 168 00:21:31,720 --> 00:21:41,720 The startling questions posed in Von Daniken's book soon inspired Scottish explorer Stanley Hall to try and solve the mystery himself. 169 00:21:43,720 --> 00:21:50,720 In 1975, Hall traveled to Cuenca to see Father Crespie's collection with his own eyes. 170 00:21:51,720 --> 00:21:58,720 I had for years been researching South America as the missing page of prehistory. 171 00:21:58,720 --> 00:22:04,720 I first heard of the Tios caves. It was an Eric Von Daniken's book, and followed it through from there. 172 00:22:06,720 --> 00:22:18,720 And one of the presents which the old priest received is a tablet with 36 writings. It's metallic tablet. No one, healthy today, was able to translate these writings. 173 00:22:21,720 --> 00:22:30,720 In 1976, Stanley Hall mounted an expedition of more than 100 people to explore Tios. 174 00:22:33,720 --> 00:22:39,720 Among them was American astronaut Neil Armstrong, the first man to walk on the moon. 175 00:22:40,720 --> 00:22:49,720 Entering the cave through a jungle entrance known to the Ecuadorian army, the explorers were fascinated by what they encountered, 176 00:22:50,720 --> 00:22:59,720 especially large areas that appear to have been excavated by someone or something. 177 00:23:00,720 --> 00:23:19,720 Head of the British Geological Group, Dr. Brian Kelly in 1976, he admitted that it was difficult for him to explain the actual large doorways that you see in these caves. 178 00:23:20,720 --> 00:23:30,720 All those Stan Halls expedition did find a tomb chamber with items dating to 1500 BC. 179 00:23:30,720 --> 00:23:32,720 A ring, a stone ring. 180 00:23:32,720 --> 00:23:40,720 The expedition found no treasure and no trace of anything that looked like the artifacts in Father Crespie's collection. 181 00:23:41,720 --> 00:23:49,720 But if Tios was not the secret origin of Father Crespie's amazing collection, where did it come from? 182 00:23:54,720 --> 00:23:57,720 Undaunted, Hall didn't give up his search. 183 00:23:58,720 --> 00:24:06,720 Fifteen years later, in 1991, the explorer tracked down an Ecuadorian named Petronio Jaramillo, 184 00:24:06,720 --> 00:24:12,720 who claimed to have entered the cave of Tios through a secret entrance back in 1946. 185 00:24:12,720 --> 00:24:19,720 And apparently, Petronio had visited this cave for the very first time when he was very young, when he was in his teens. 186 00:24:20,720 --> 00:24:27,720 He said that he had to dive underwater, go in this underwater tunnel and then come up. 187 00:24:28,720 --> 00:24:38,720 Jaramillo told Hall he wandered through chamber after chamber of ancient relics, including a vast room of books made from gold and other metals. 188 00:24:38,720 --> 00:24:41,720 Books with unrecognizable writing. 189 00:24:42,720 --> 00:24:48,720 Possibly, like that on one of the metal tablets in Father Crespie's collection. 190 00:24:50,720 --> 00:24:53,720 The other things looked like formulas and so on and so on. 191 00:24:53,720 --> 00:24:57,720 So, it was one spectacular statement after another. 192 00:25:00,720 --> 00:25:06,720 Some argue whether or not an ancient civilization had come down to Earth and had used this cave system 193 00:25:06,720 --> 00:25:12,720 to leave certain artifacts of their civilization behind for us to recover. 194 00:25:14,720 --> 00:25:25,720 Unfortunately, before he could guide Stanley Hall to the underwater cave entrance, Petronio Jaramillo died, taking the secret to his grave. 195 00:25:26,720 --> 00:25:37,720 Stanley Hall himself died in 2008, before he was able to renew his search for the so-called metal library. 196 00:25:40,720 --> 00:25:46,720 Fortunately, Stanley Hall's daughter Eileen has decided to continue her father's work. 197 00:25:46,720 --> 00:25:53,720 Unless we find this treasure, unless we can see, translate the writing, it's still a big question mark over. 198 00:25:53,720 --> 00:25:56,720 Who wrote it? Why they put it there? Who put it there? 199 00:25:57,720 --> 00:26:02,720 But when Eileen Hall began to look for the location of Father Crespie's original artifacts, 200 00:26:02,720 --> 00:26:11,720 she learned that much of the priest's collection had mysteriously vanished, shortly after his death, in 1982. 201 00:26:12,720 --> 00:26:17,720 But why? Had Crespie's artifacts fallen prey to thieves? 202 00:26:18,720 --> 00:26:22,720 Or might the schwar have taken their treasure back into the cave where they found it? 203 00:26:24,720 --> 00:26:31,720 Whatever the answer, Eileen Hall has continued to research other artifacts from elsewhere in Ecuador. 204 00:26:32,720 --> 00:26:38,720 And like Father Crespie's objects, some seem to have uncanny resemblances to other cultures, 205 00:26:38,720 --> 00:26:45,720 that according to mainstream archaeology, ancient Ecuadorians could not have had any knowledge of. 206 00:26:47,720 --> 00:26:53,720 This collection is made up of what my father believed to be the formative cultures of Ecuador. 207 00:26:54,720 --> 00:26:59,720 This is from the hostile culture from 600 BC to 1600 AD. 208 00:27:00,720 --> 00:27:04,720 And this is very human-like, but at the same time some features have been exaggerated. 209 00:27:04,720 --> 00:27:13,720 Here you've got the smaller face with the kind of bigger ears and the elongated skull shape in the head. 210 00:27:14,720 --> 00:27:21,720 The top of this head looks like an elongated cranium, an elongated skull, 211 00:27:21,720 --> 00:27:28,720 and it is identical to this Egyptian statue that we find all over Egypt. 212 00:27:28,720 --> 00:27:38,720 To see this picture right here and compare it to the Egyptian bust we see right here, it's uncanny. 213 00:27:38,720 --> 00:27:41,720 The head shape is identical. 214 00:27:43,720 --> 00:27:52,720 Do Stanley Hall's artifacts show evidence that Egyptian culture could have crossed the ocean to influence South American culture? 215 00:27:54,720 --> 00:27:59,720 Or is it possible that both were influenced by another culture? 216 00:27:59,720 --> 00:28:02,720 One from beyond our world. 217 00:28:03,720 --> 00:28:12,720 If so, were the strange writings inscribed on Father Crespie's metal tablets actual messages from an alien world? 218 00:28:14,720 --> 00:28:19,720 My father went as far as saying it was possibly an advanced civilization, 219 00:28:19,720 --> 00:28:23,720 but we can't know for certain until this library is found. 220 00:28:26,720 --> 00:28:32,720 So this metallic library is still there in Ecuador in a subterranean cave. 221 00:28:34,720 --> 00:28:40,720 Since there are still Indian tribes living there, they are still protecting the old treasure. 222 00:28:43,720 --> 00:28:49,720 So it's going to push the boundaries of academia once this cave system has been found. 223 00:28:49,720 --> 00:28:54,720 And whether it is Inca or extraterrestrial, it doesn't really matter at this moment in time. 224 00:28:54,720 --> 00:28:57,720 Let's get to this cave and see what is in there. 225 00:28:59,720 --> 00:29:03,720 Perhaps Taos has yet to reveal all of its secrets. 226 00:29:03,720 --> 00:29:07,720 But more than 700 miles to the north, there is another cave. 227 00:29:07,720 --> 00:29:15,720 One that may prove that the Mayan underworld and the terrifying gods who ruled it were not only very real, 228 00:29:15,720 --> 00:29:19,720 but thirsty for human blood. 229 00:29:26,720 --> 00:29:28,720 The Yucatan Peninsula. 230 00:29:30,720 --> 00:29:33,720 One of Mexico's premier tourist destinations. 231 00:29:37,720 --> 00:29:45,720 Besides scenic beaches, the area is covered by thick jungle and pockmarked by massive sinkholes known as cenotes. 232 00:29:48,720 --> 00:29:52,720 The ground beneath the jungle is also honeycombed with caves. 233 00:29:54,720 --> 00:30:02,720 But here, in 2007, Mexican archaeologist Guillermo de Anda found a cave like no other. 234 00:30:03,720 --> 00:30:14,720 Following clues in the records of 17th century Spanish priests that hinted at the existence of a mysterious underground Mayan temple deep in the jungle, 235 00:30:16,720 --> 00:30:20,720 De Anda found a series of caves near the village of Tansi Beachen. 236 00:30:24,720 --> 00:30:27,720 Caves not seen for hundreds of years. 237 00:30:28,720 --> 00:30:32,720 And with entrances submerged beneath centuries of floodwater. 238 00:30:36,720 --> 00:30:40,720 Sometimes we have to dive into these caves. Sometimes they go very deep. 239 00:30:42,720 --> 00:30:50,720 The average of our research is about 140, 150 feet, but we know of caves much deeper than that. 240 00:30:51,720 --> 00:31:00,720 At first, De Anda and his team found carved stone heads and broken pillars with 1900 year old Mayan inscriptions. 241 00:31:03,720 --> 00:31:14,720 We have found columns under the water. And these columns are amazing because some of them are 5 feet high and at least 10 feet wide. 242 00:31:15,720 --> 00:31:25,720 But as De Anda surfaced in the dry areas of the cave, he found what he believed to be the remains of a massive underground temple complex, 243 00:31:26,720 --> 00:31:31,720 including a concrete road, a crumbled pyramid and bones. 244 00:31:33,720 --> 00:31:35,720 But why was it here? 245 00:31:36,720 --> 00:31:45,720 The Mayans themselves have a very intriguing legends of an underground world called Sibalba. 246 00:31:46,720 --> 00:32:00,720 And it's believed now by archaeologists that what they found is what the Mayans thought was the entrance to this legendary underground world that features prominently in the Popul Vood. 247 00:32:01,720 --> 00:32:08,720 Could this dark and mysterious cave really be the underground world mentioned in the Mayan legends? 248 00:32:12,720 --> 00:32:21,720 According to the Popul Va, the written record of Mayan mythology, the underworld kingdom of Sibalba, meaning the place of fear, 249 00:32:21,720 --> 00:32:37,720 was ruled by the cruel lords of the dead, who made those who entered their realm pass through a series of torture chambers, involving blood, darkness, cold, knives, bats and jaguars. 250 00:32:38,720 --> 00:32:47,720 We see here in this one archaeological spot an actual physical representation of what the Mayans felt the soul had to go through. 251 00:32:48,720 --> 00:32:56,720 Might perhaps this cave of stalactites, sharp enough to pierce flesh, represent the room of knives in the Popul Va. 252 00:32:57,720 --> 00:33:04,720 There is also a room of bats and a trench that might once have been filled with blood, like the river of blood that Mayan pilgrims had to cross over. 253 00:33:05,720 --> 00:33:12,720 There are places of cold and darkness and even a room with the bones of jaguars. 254 00:33:14,720 --> 00:33:19,720 These caves were littered with large patches of spiders and reptiles. 255 00:33:19,720 --> 00:33:23,720 All types of tumultuous things that a human really wouldn't want to be exposed to. 256 00:33:25,720 --> 00:33:32,720 Although some archaeologists claim this unique site was simply modeled after the description of Sibalba in the Popul Va, 257 00:33:33,720 --> 00:33:39,720 Deanda insists that items from the cave date back to a time centuries before the Mayan holy book was written. 258 00:33:39,720 --> 00:33:46,720 It's not that there was this document and they tried to imitate what the document said. 259 00:33:47,720 --> 00:33:49,720 I think it's all the other way around. 260 00:33:50,720 --> 00:33:55,720 We believe that we have found the particularity of the center of the part of Yucatan. 261 00:33:56,720 --> 00:33:59,720 This is why we do believe it was a real place. 262 00:33:59,720 --> 00:34:04,720 But if Sibalba is real, were the Lords of the Dead also real? 263 00:34:05,720 --> 00:34:09,720 And if so, who or what were they? 264 00:34:11,720 --> 00:34:17,720 According to the Chilambalam book, which is the book of the Jaguar priests, it says in there, 265 00:34:17,720 --> 00:34:24,720 that at that time the road to the stars descended from the sky and the 13 and 9 gods came to Earth. 266 00:34:25,720 --> 00:34:29,720 I'm sorry, road to the stars descended from the sky. 267 00:34:30,720 --> 00:34:31,720 Can it be more clear? 268 00:34:32,720 --> 00:34:34,720 The stars descended from the sky? 269 00:34:35,720 --> 00:34:36,720 No, it's not. 270 00:34:37,720 --> 00:34:39,720 It's the stars that descended from the sky. 271 00:34:39,720 --> 00:34:41,720 The gods came to Earth. 272 00:34:42,720 --> 00:34:45,720 I'm sorry, road to the stars descended from the sky. 273 00:34:46,720 --> 00:34:47,720 Can it be more clear? 274 00:34:48,720 --> 00:34:49,720 I don't think so. 275 00:34:50,720 --> 00:34:56,720 Right there we have a direct reference to someone that has arrived from outer space and we have a written record about this. 276 00:34:59,720 --> 00:35:05,720 Could the Lords of Sibalba and other Mayan gods really have been extraterrestrial travelers? 277 00:35:06,720 --> 00:35:11,720 If so, why did they display such a thirst for blood and torture? 278 00:35:13,720 --> 00:35:17,720 I do not believe human sacrifice was originally taught by the ETs. 279 00:35:18,720 --> 00:35:22,720 I believe it came in the aftermath of when the original teachers of humankind had arrived. 280 00:35:25,720 --> 00:35:33,720 The ancient gods, which were really just humans from another world, withdrew from the area and the people became distraught. 281 00:35:33,720 --> 00:35:42,720 The more they became distraught, the more they took the original mythology and interpreted it in a much more literal way. 282 00:35:43,720 --> 00:35:49,720 So what might have started out as the myth about the sun dying and being reborn when it sinks below the horizon 283 00:35:50,720 --> 00:35:55,720 becomes literally the idea of killing people to make sure that the sun is going to come back up. 284 00:35:56,720 --> 00:36:03,720 As archaeologists and explorers continue to uncover sites where legend and reality meet, 285 00:36:04,720 --> 00:36:13,720 would there be even more evidence that mankind's history on this planet is much more profound than what we currently understand? 286 00:36:14,720 --> 00:36:21,720 There are those who believe the secret lies even deeper within the Earth, as deep as its very core. 287 00:36:26,720 --> 00:36:39,720 The North Pole, a seemingly endless wasteland of Arctic ice, shrouded in darkness for six months of every year. 288 00:36:40,720 --> 00:36:47,720 Here there is no food, no shelter, not even a cave to hide from the slashing winds 289 00:36:48,720 --> 00:36:51,720 and temperatures that can dive to 90 degrees below zero. 290 00:36:52,720 --> 00:37:02,720 But according to mainstream geology, beneath the pole and the Arctic Ocean lies the Earth's mostly rocky crust, up to 30 miles thick. 291 00:37:03,720 --> 00:37:12,720 Below this is molten rock, heated by the planet's spinning core, with a solid center of iron and nickel the size of the moon. 292 00:37:13,720 --> 00:37:21,720 Scientists have deduced this information from measurements of Earth's gravity, magnetism and seismic waves. 293 00:37:23,720 --> 00:37:26,720 But no one has ever seen these areas. 294 00:37:27,720 --> 00:37:34,720 Could the frozen surface of the pole be hiding a gateway to a world within our surface world? 295 00:37:37,720 --> 00:37:40,720 There are those who believe the answer is yes. 296 00:37:43,720 --> 00:37:48,720 And what they believe is known as the Hollow Earth Theory. 297 00:37:49,720 --> 00:37:56,720 The Hollow Earth Theory is that this Earth is not molten inside, it is actually hollow. 298 00:37:57,720 --> 00:38:00,720 And that suspended in the hollow of the Earth is an inner sun. 299 00:38:03,720 --> 00:38:11,720 Surprisingly, the notion of a Hollow Earth was first given scientific credence by one of the founders of modern astronomy. 300 00:38:13,720 --> 00:38:23,720 The idea that the Earth might be hollow as a scientific notion dates back to the astronomer Edmund Haley, who is best known for his comet. 301 00:38:25,720 --> 00:38:41,720 In 1691, he presented to the London Royal Society his hypothesis that the Earth is hollow and contains several little spheres inside, sort of like those Russian Matryoshka dolls. 302 00:38:42,720 --> 00:38:46,720 He was hypothesizing this for a very practical reason. 303 00:38:47,720 --> 00:38:52,720 The Earth's magnetic pole moved a little bit every year to the west. 304 00:38:53,720 --> 00:39:00,720 And his idea was that our outer sphere had inner spheres that turned independently of the outer one. 305 00:39:02,720 --> 00:39:07,720 He also suggested that these interior spheres would also be able to support life. 306 00:39:07,720 --> 00:39:22,720 In 1818, former U.S. Army Captain John Cleve Sims Jr. announced that there were vast openings at each pole, where we could enter inner Earth. 307 00:39:24,720 --> 00:39:29,720 With Sims, the idea of a Hollow Earth gets tied into exploring for the pole. 308 00:39:30,720 --> 00:39:33,720 At this point, nobody had actually seen Antarctica, for instance. 309 00:39:34,720 --> 00:39:47,720 The Hollow Earth theory again captured the public's imagination in 1864 with the release of Jules Verne's second novel, A Journey to the Center of the Earth. 310 00:39:48,720 --> 00:39:56,720 The novel takes an Icelandic guide and a professor and a young man down into the center of the Earth. 311 00:39:57,720 --> 00:40:02,720 The Journey to the Center of the Earth could really have been called a journey to the center of geology. 312 00:40:03,720 --> 00:40:11,720 Geology and paleontology were a very hot topic in the early 1860s, and there was a lot of discussion of that in Journey to the Center of the Earth. 313 00:40:12,720 --> 00:40:23,720 But while Verne popularized the idea that extinct life forms might still exist inside the Earth, others envisioned that the Earth contained advanced underground civilizations. 314 00:40:24,720 --> 00:40:36,720 Supposedly, they have advanced technology. They've got ray guns and special weapons, and even they have flying saucers and other craft like that. 315 00:40:37,720 --> 00:40:46,720 But is there any evidence that such fantastic claims could be true? And has anyone actually been to the world within our Earth? 316 00:40:47,720 --> 00:40:57,720 Proponents of the Hollow Earth theory say yes, and that one of the explorers was no less illuminary than famed polar pioneer Admiral Richard E. Byrd. 317 00:40:58,720 --> 00:41:07,720 In the 1920s, Byrd made world headlines by flying over the North Pole and by becoming the first man to fly solo over the South Pole. 318 00:41:08,720 --> 00:41:14,720 But Hollow Earth theorists believe that the famous explorer went even farther. 319 00:41:15,720 --> 00:41:25,720 And that, on February 19, 1947, Admiral Byrd piloted a plane through a hole near the North Pole into the interior of the Earth. 320 00:41:26,720 --> 00:41:32,720 Flying saucer type craft to control of his airplane was some kind of tractor beam. 321 00:41:32,720 --> 00:41:44,720 In the land of them nearer inner Earth city, and the meshes that they had for us was that they consider themselves the guardians of this planet. 322 00:41:45,720 --> 00:41:50,720 He says, we don't approve of you people using nuclear weapons. 323 00:41:51,720 --> 00:41:56,720 We had just blown up a couple of cities in Japan a couple of years before. 324 00:41:57,720 --> 00:42:00,720 So this was the meshes that he was given. 325 00:42:01,720 --> 00:42:07,720 But when he got to Washington, they put a lid, a secrecy on this that this was not to go out. 326 00:42:10,720 --> 00:42:21,720 Some say Admiral Byrd's own account of this flight into the Hollow Earth is detailed in his secret diary published in the 1990s, almost four decades after his death. 327 00:42:22,720 --> 00:42:34,720 But skeptics claim the diary is a forgery, and point out that in February 1947, at the time Admiral Byrd was supposedly visiting this other world underneath the North Pole. 328 00:42:35,720 --> 00:42:46,720 He was actually part of a vast, 4,700 man naval exploration called Operation High Jump, 12,000 miles away, near the South Pole. 329 00:42:47,720 --> 00:42:55,720 But could Byrd's inclusion in this large military operation at the South Pole have been merely a cover story? 330 00:42:56,720 --> 00:43:04,720 Some people claim it was, and this allowed him to slip away to the other end of the planet, unnoticed by the media. 331 00:43:05,720 --> 00:43:16,720 Admiral Byrd, the rumor was, found a world of flying machines and people and more advanced than us, and that they helped him and then he left again. 332 00:43:17,720 --> 00:43:21,720 It's a myth. Nobody's really been able to prove it, but it's a great myth. 333 00:43:24,720 --> 00:43:30,720 Could there really be vast open spaces within the Earth where advanced civilizations live? 334 00:43:31,720 --> 00:43:41,720 Could extraterrestrial gods really have come here centuries ago and hidden the evidence of their journeys deep within caves and tunnels? 335 00:43:42,720 --> 00:43:47,720 Perhaps we've only just scratched the surface of our planet's underground mysteries. 336 00:43:48,720 --> 00:43:57,720 If so, what clues to our distant past might still be waiting to be found and hiding in the darkness?
