“That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.The aggregate of our joy & suffering, thousands of confident religions, ideologies, & economic doctrines, every hunter & forager, every hero & coward, every creator & destroyer of civilization, every king & peasant, every mother & father, hopeful child, inventor & explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint & sinner...lived there-on a mote of dust suspended in a sunbeam."
