You're being downvoted because you missed the point and continue to do so. Nobody said that earth created those things, or that going into space would somehow make us more compassionate. The point is that being spread out across interplanetary distances reduces the need for bad people to take truly drastic measures, and mitigates the damage that any particular disaster can do. Even if we a madman managed to blow up the entire world, as long as he can't do so to every world that humans are inhabiting simultaneously, humanity will live on.
