we're constantly talking about going to the moon or mars to one day establish colonies there. is it possible that thousands of years ago people on mars thought the same thing and came here to colonize earth. would this explain us better than evolution? and every month now it seems theres something new coming out about mars?
p.s. i know the question posed is misleading but i wanted a ot of ppl to look at and provide comments...

Well its a good thought but there are several problems with that.
First of all, we have seen Mars, and if there was a whole civilization that was technologically advanced enough to fly people off and colonize on earth, then we would be able to see traces of civilization and living cells probably? Maybe not.
But also, why would a whole civilization ship people off to another country when there was no problem with mars in the first place. Thats like hearing an announcement on the radio saying "Pack up your stuff, EVERYONE in the WORLD is being moved to the moon! Nothing wrong with the earth but we are moving anyway."
Also, we have scientific evidence proving evolution so it would be hard to throw all that aside and instead assume that we were once martians but were moved here for some reason.
We would also have records of this move of course. Its just like people from Great Britain being colonized in the New World. People would write stuff down and we wouldnt be completely oblivious to the fact that we once lived on another planet. Also humans cant possibly survive on mars because it gets too cold.

I suspect that there is microbial life in Mars right now, 1/2 mile down under the permafrost where liquid water still flows. If we can get a way to drill down that far and collect a sample we'll be able to culture it. Mars life will be found to be related to Earth life via panspermia 3 or 4 billion years ago. The question is; Did life arise on Mars first and get transported here, or vice versa???
There is also a theory that it took Earth life a "longer than average" stretch of time (before it became multi-cellular) because there was not enough oxygen in the atmosphere to support more complex life until about 650 million years ago. Plate tectonics and an active, alive young Earth vigorously and quickly recycled her crust, causing it to combine with other compounds. The initial oxygen emitted by microbes had to combine with all that iron that was laying around first, before it could start to build up in the air.
The same is NOT true of Mars. She lost her internal heat quickly and any plate tectonics going on would have ground to a halt. So if there was photosynthetic microbial life in her primeval oceans, oxygen could have built up in the air much more quickly instead of getting sucked out by material getting oxidized. It is possible that complex, multi-cellular life forms may have evolved very soon. Perhaps within 500 million years, before Mars grew cold and dried out. If so, we will find fossils.
But I doubt there will be any humanoid remais.

The idea that we came from Mars is pretty flawed. Obviously, if that were the case, how do you explain the missing technologically advanced civilization that got us here? We can find all kinds of stone tools and remains from ancient man, but I haven't seen a single space ship and I think it would preserve better than some things that have been preserved. Plus, nothing has been found on mars that indicates a civilization was there. Caves on Mars is a natural formation, not evidence of things living there.
I think evolution is a plenty satisfactory explanation for biodiversity and progression of species as seen in the fossil record.

Interesting concept for a story but not possible. If it was so our prior civilizations would of been way more advanced then we are today. That is the simplest answer I could give you.

And they just happen to have DNA that was 98% similar to Chimpanzees? Or did they bring all the animals with them?

Man...If somebody dropped us off here from mars, then we really got HOSED! Not one lazer gun or computer, or rocketship, or anything? Just "rub sticks together to make fire, and make tools from rocks, ok guys?" Screw those Martians!

you may be right but there could be intelligent life out there (aliens) too
