They need to detect us. If they've not detected us, why would they

in your attempt to contact ETI's, broadcast to apparently empty

I would focus my efforts on stars with planetary systems.

The problem is that you don't seem to realize that the detectability
issue works both ways. If ET can't detect our planetary system, why
would ET broadcast at our star?

If ET in our galaxy exists at all, it knows darn well that are here, 
because it almost certainly colonized the entirely galaxy many millions 
of years ago.

Correct. Though I think it's also not right to exclude Extra
Dimensional creatures, natives non-'homo sapien' sentient creatures on
Earth, and so on.


Of course, on why there seems to be lacking a sort of massive
interstellar and/or interstellar travels.

It could be either that they are:

- extinct

- no longer can do interstellar and/or interplanetary travel


The first is possible, but the latter is also possible.

Below is a a translation of an ancient scripture, it seems to be kinda
like a statement of an interstellar travel who no longer can do
interstellar travel (maybe even interplanetary travel).

"And we pried into the secrets of heaven; but we found it filled with
stern guards and flaming fires."

"We used, indeed, to sit there in stations, to hearing; but any who
listen now will find a flaming fire watching him in ambush."

"And we understand not whether ill is intended to those on
earth/world, or whether their Lord intends to guide them to right
conduct."

"There are among us some that are righteous, and some the contrary: we
follow divergent paths."

Yet no ETs seem to be in our solar system,

Well... That depends on one's point of view.

We are being constantly bombard by the news, fact books, 'experts',
and so on that there are no ETs in our solar system or on/in our
planet. But are these things true or not? If these things aren't true,
is it just an honest mistake or there's something more sinister behind
it?

But then again, we have too much more important things to think about
than ETs. So... Who cares about ETs anyway? And maybe the sentiments
are the same.

Then there's the term "ETs", Extra Terrestrial (outside Earth) isn't
the only place where we could find sentient creatures, I mean there
could be Extra Dimensional creatures, natives non-'homo sapien'
sentient creatures on Earth, and so on.

To keep saying on ETs is kinda like anti-Earth. I find that in recent
decades, there have lots of anti-Earth propaganda, this is kinda odd,
considering men probably would be more interested on chasing girls and
more girls than focusing on the stars.

which indicates that either (1) there are no ETs out there,

Possible.

or (2) they have 
specifically avoided our solar system.

The PD?

Many will break the PD, each person has his 'own way'.

In the case of option (2), I 
think it is by far most likely that our system has been avoided because 
it harbors life.  It's possible that there is something else special 
about our solar system that makes it worth preserving in its natural 
state, but I doubt it.

Maybe it's just us that they are trying to avoid? Of course some
people will then twist this into that we are just so horrible that
nobody wanted to be with us, but... if we are that horrible, we would
have been destroyed a LONG time ago.

It's possible that it's the other way around, maybe because there are
something so special about us that made us go on life without any
interference.

Maybe we are the youngest sibling and the head of the family said to
the rest of the family to not interfere with the development of the
youngest sibling.

Now, SETI proponents often seem to imagine a third option, which is that 
there is an ET civilization out there which just happened to evolve at 
exactly the same instant in time as us.

It's kinda like searching for the kids next door, that is EXACTLY the
same age as the searcher, with the difference of the age is only a
fraction of a fraction of a nanosecond.

It's almost as much as an impossibility of manually crashing two
aircrafts into two towers, then again, it's more impossible than that.

A fourth proposal, that ETs are out there and much older than us but for 
some reason are all stay-at-homes with no interest in colonizing the 
galaxy, is just as ludicrous.

Of course, there's also the possibility that there are interstellar
travelling civilizations that started from Earth itself and/or already
considered Earth as home.

So.  Either ET's not out there, or it's right next door and knows very 
well that we're here (and probably speaks all our major languages too).

It's probably next door, though maybe for some of them the term should
be ED instead of ET. And also some of them might be natives of this
planet that lives long before our ancestor ever showed up.

If there are non-'homo sapien's living with us on this Earth, they are
surely hide themself pretty good. Maybe the keyword here is "hide".
 

In the latter case, if it wanted to contact us, I don't think it would 
require scanning millions of channels with sensitive detectors -- there 
would be no missing it.

Correct. But what if they are ordered on not to contact us?

Of course some will disobey the order, but probably will be done
incognito.



Personally, what we should is YETI, Yell at Extra Terrestrial
Intelligences. We get the strongest transmitter, then transmit
everything we know to outer space (not simple Hi or Hello, but a total
scream of everything we know), so if there are ETs out there, there
are few possibilities:

- ETs who get addicted by us, so much that they are willing to go to
Earth to meet the superstars (humankind). They might even go so far
back to Earth to find out how their favorite soap opera end because
they missed the first run and reruns (if there was any).

- ETs who get bugged so much by us, so much that they would go to
Earth to complain. But then again, if they were bugged by us that
much, they probably would just send a letter of complain instead.

- ETs who get earmuffs to silence our transmissions.


Of course, if there are no ETs listening to our transmissions, at
least these will be a nice time capsule stuff for future generations
to heard (provided they travel faster than then transmissions and then
able to receieve). Besides, if the humans will be there to heard, they
would be the ETs.
