what do you think aliens really are?

All living forms of life on Earth are all related to each other (Within the DNA structure). This would fully support the evolution process - In other words, no outside intervention.

Why would an 'advanced' former member of the human race, not come back and colonize his former home? Why wait for the evolution process?

If the former inhabitants of Earth were able to build a space faring vessel, a craft that could navigate deep space, a craft that could support all man's needs (food, water, oxygen etc..) ....

Why could they not deflect an asteroid / meteor???

It was obvious that they detected it in time - hence the selection process to sustain the human race via reproduction....

Finally.. Where do these former earthlings live?? It's a long way to the nearest coffee shop outside of our planet. Is it logical to expect people / aliens to live in a spaceship hovering above the atmosphere 'watching' us?? Could you sit by an ant nest looking at it all day for an eternity???

Commonsense must prevail..... Without a scratch of evidence to support such a theory,, it probably means that it didn't happen... (The evidence against such a theory is all around us)

I think it's a cool idea - nobody really knows if there is life somewhere else. The only problem is that there is no large fossil evidence of a human popluation that was suddenly wiped out. They hypothesize that dinosaurs were wiped out by a meteor (led to their extinction), but that was many millions of years before homo sapiens appeared (using carbon dating).

Ancient civilizations have always fascinated me more that modern history, just because there is so much mystery surrounding their culture. Most ancient civilazations had some brutal rituals. I visited Aztec temples in Mexico when I was a kid, and there was a narrowing crawl space in which they sent a person to be executed - if they decided to come out the other side, there was a pedestal surrounded by a pit where they were killed (I'm not sure how). And this civilization is only thousands of years old.

I believe humans are still in the dawn of their evolution, and if there are aliens out there, they would be so different and incomprehensible - like nothing we could fathom on Earth.

If they would come on a meteor, They'd probably be burned in the process haha. Unless they can withstand fire and heat.

I really think that Europa has life under its sheet of ice. But not like HUGE fish or anything, small bacteria and critters. :)

Its possible that they could destroy Earth, but its highly unlikely. And if there's no other living race in our solar system. Then it would takes sooooooo many years for them to get here, and we'd be prepared way before hand lol, Or I'd hope so :D

You do have a very good point. I would never imagine such a brilliant idea of aliens in that perspective. Yes it could be possible. Could be from Earth in the past, but could also be aliens observing us. We have some clues that point out to aliens observing us, with UFOs and ancient pictures of other "creatures" helping civilizations in the past, or the ancient civilizations looking to the sky especially the stars. Aliens could have helped our ancestors build architect such as the Great Pyramids or Stone Henge all having to do with star relations. your point could be possible.

If intelligent archaeologists will be around millions of years from now, they will find, embedded in rock, cell phones, computers, car parts and many other signs of an advanced civilization as we find the stone axes of Homo erectus today. But today's archaeologists do not find signs of such an advanced civilization from so long ago.

Nonsense. in case you think of that existence became presented to Earth from another area, or seeded by potential of "extraterrestrial beings," then all you have carried out is to head the ingredient of beginning place of existence to a pair different area. you nevertheless would desire to describe the <beginning up> of a practicable existence style. If we are saying "It would desire to have occurred someplace else", then we get rid of incentive to check out, hit upon and test to locate a mechanism for beginning place right here, on our very own planet. it somewhat is ineffective. technological awareness seeks suggestion, solutions, know-how in step with info and evidence supported theories. to assert that extraterrestrial beings did it, or that a "god" did it, is an answer the promotes and prolongs lack of awareness.

You ask and answer your own question and do not leave room for interpretation. The idea you present has been offered before and I will answer with the same I always do. Show me the evidence.

They're from mexico, and my best customers.

mexicans.
