OK, let's say, we found signs of ancient life on other planets. Can you imagine the consequences if life forms from other planets, which we will bring, will be able to adapt in the luxurious conditions for life on Earth?
Add: Although quite a lot of animals and plants have long been like aliens
There is a possibility that we (Homo) are aliens to Earth actually. Imagine Earth without people. It's a completely different planet will be.
This version is well-coordinated with the Bible to some extent, by the way.

No, there isn't.
Why not?
Do you understand biology and how evolution works? How exactly would our specific species (which is an arbitrary distinction anyway) come from a place other than Earth and have an exact evolutionary compatibility as Earth yet somehow we lost all the history and technical know-how of our arrival? Ridiculous idea.
Why is my impression that the nature of the Earth do not care for all human achievements.
Of course, each of us generates a certain energy, which we can not even understand.
When run out of natural resources of the Earth, my grandchildren on Mars or Venus will need to live, or what?
Well, even considering that I was born in Russia, and I know as well as I can survive in conditions that for any Europeans seem hell, other planet is a bit more complicated

Oh yes, I do. But I never discount anything, even that which is improbable.

It would just be really weird for proto-humans to have naturally evolved on earth, and then right as homo sapiens were about to have evolved, homo sapiens walk off a space ship instead.
