Most planets/moons in our solar system would probably be MORE inhospitable than the Earth after an asteroid hit on the Earth.
I suppose to colonize a place like Mars or Titan, we would need to build grand pressurized structures, large "greenhouses" for growing food, large
storage tanks for water, among other things vital to keep the species going.
Do you think it may be possible that it would be easier to build such "shelters" on Earth, even an Earth that is not fit for human habitation
Of course, if the kind of catastrophe you are talking about is one that causes the entire surface of the planet to be wiped clean -- either by global
flood or by the entire crust becoming molten -- then I agree that we could not survive here. Or, as you said, we may never see it coming in the first
However, if you are talking about the kind of impact event that wiped out the dinosaurs (or even one larger than that) in which the surface stays in
tact but most living things die, then I would say it would be easier to build the necessary shelters here on Earth.
Would the post-impact Earth really be more inhospitable than, say, Mars?
