“If I died on a lifeless world, a world that could sustain some form of life if it were tenacious enough, organelles within each cell of my body would survive and evolve. In perhaps a thousand million years, that world would be as full of life as this one.” “… it would?” “Yes. Our ancestors have seeded a great many barren worlds that way. Nothing is more tenacious than the life we are made of. A world of life from apparent death, from dissolution. That’s what we believe in.”
