There is no other civilization in the solar system.

If it's humans vs alien slime mold, I stand for humans.

Right. Seeding life onto lifeless planets takes a long time, but it is a moral imperative. We are the only life in the solar system, and maybe even in our galaxy.

BTW, the Earth is going to fry in 100m years. We'd better learn how to colonize the other planets.
