I've recently heard that in order to prevent the extinction of humanity, it would be a good idea to get several colonies up and running off-world. So if we colonize Mars, and then there's a nuclear war on earth, or a huge asteroid kills everything, humanity would still stand a chance on Mars.
But all things are relative.
If one mega-disaster can take out Earth, an even bigger disaster could wipe out the solar system. Or the galaxy. Maybe even the universe. So not only must we have outposts on other planets, we need them in other solar systems, galaxies, universes, and maybe even times.
