Well, i don't even know if there's evidence that life started on earth but there probably isn't any saying otherwise.

Ok, monkey, human etc. whatever the ancestor.. I haven't said anything against evolution, just the possibility of life starting elsewhere but evolving here on earth.

well trickster, I gotchya.
to enlighten every one here, I think you may be referring to the first enzymes, dna, or fully grown bacteria that STARTED to evolve LEADING up to these worms birds and monkeys.

I've heard other theories that life structures where stuck in meteors that hit earth, releasing themselves and copies and they've been thriving ever sense.
unconfirmed though and I don't know if it could be.
BUT if its true, it is very likely that some of these meteors might have ended up on other planets as well.
so far we have found NO life anywhere but here on earth.
maybe our conditions where the only right ones.

If so, how did it get here? Flying saucers intentionally seeding the planet? I suppose that is a possibility, but we have no evidence for that.
Some people have speculated that single cell life could have started on Mars or even Venus first and then come here by riding on a meteor. But I find that HIGHLY improbable. For one thing, there is no life on Mars or Venus now. And for another thing, the meteor would have to have been blasted off Mars or Venus by a pretty big meteor impact there, and that would almost certainly kill any life that might be there to ride the debris into space. Some people say that very hardy spoors or whatever could have survived that, and the long trip through space too, but I don't think the probability is high enough to seriously consider.

Perhaps you did, but the rest of humanity evolved here and we are genetically related to every living thing on earth from worms to redwoods. See that bird in the tree outside your window? You and he share a common ancestor. VERY long ago. That would not be true if we came from another world.

just to muddy the waters a bit...
meteors fall into several categories, the two main ones are 1) ferrous and 2) carbonaceous.
glycine and benzene have been discovered in space and while it seems like a longshot... its POSSIBLE that meteors containing complex carbon molecules fell on Earth long ago and started the whole thing.

as you know that scientists have told us that the earth was created 4 billoion years ago and a large number of animals had came and gone and after that humans arrive.o i dont think that we all have come from other planets but i am sure that there are creatures out there like us.
