We may "kill" the planet, though history tells us even if we don't, a giant rock hitting the Earth wiped out the Dinosaurs so that could and probably will happen again. If we found a similar rock on the way today I'm not sure we could stop it unless we have decades to do so. But this alone should be enough reason to colonize another planet, to avoid the extinction of our species the way the Dinosaurs were made extinct.

Juan. It would be highly unlikely that any type of explosion would "press corpses into the ground."
That concept defies realty. Neither heat or pressure would do that.
One famous, anonymous Hiroshima victim left only a "shadow", permanently etched into stone steps near a bank building.

However first I think we should determine if there's life already on, or "in" Mars (maybe in water just below the surface), and if there's life already there, maybe we shouldn't colonize it, and leave Mars to the Martian life that's already there.
