"Look again at that dot. That's here. That's home.
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 and suffering, thousands of
confident religions, ideologies, and economic
doctrines, every hunter and forager, every hero and
coward, every creator and destroyer of civilization,
every king and peasant, every young couple in love,
every mother and father, hopeful child, inventor and
explorer, every teacher of morals, every corrupt
politician, every "superstar", every "supreme
leader", every saint and sinner in the history
of our species lived here - on a mote of dust
suspended in a sunbeam."
Carl Sagan, from "Pale Blue Dot"
