One more very minor step towards making the human race meteor-proof.

Our biology precludes that. We are adapted to life on earth. Sad to say but we should be seeding tardigrades, not humans, if we care about sustaining earth life after earth is destroyed.

We use technology to do many things we are not biologically capable of. If we can use technology to remotely explore inhospitable environments, we can also use technology to wrap ourselves in a hospitable environment.

I kind of have a soft spot for the human race, I think it's worth the extra effort to try, at least.
