We are pretty sure that an impact liquified the entire surface of the Earth (creating the Moon by casting a big chunk of molten material into space). So clearly the “greatest imaginable” impact does not leave the Earth more habitable than the alternatives.

That was an impact by a Mars-sized body early in the history of the solar system. That's not going to happen again. The dangers now come from objects a few kilometers across, at most.
