And then thousands if not millions of years later, those same rocks, now meteoroids themselves, land on another planet. And those little micro-organisms find themselves on a new planet in which the atmosphere doesn't kill them. Slowly over billions of years, the micro-organisms evolve into stuff.
They thought they found proof of something similar a while back in a martian meteorite. They thought it was a fossil of a martian micro-organism. But it turned out not to be. But the theory is actually sound.
