"Homo sapiens. What an inventive, invincible species.
It's only a few million years since they've crawled up
out of the mud and learned to walk. They've survived cosmic wars and holocausts, and now here they are
amongst the stars, waiting to begin a new life, ready to outsit eternity. They're indomitable. Indomitable!" -
