Everything you’ve ever known…

The lunar flights give you a correct perception of our existence. You look back at Earth from the moon and you can put your thumb up to the window and hide the Earth behind your thumb. Everything you’ve ever known is behind your thumb, and that blue-and-white ball is orbiting a rather normal star, tucked away on the outer edge of a galaxy. You realise how insignificant we really all are. Everything you’ve ever known – all those arguments and wars – is right behind your thumb.

everything you’ve ever known … all of human history has happened on that pale blue dot.

From this distant vantage point, the Earth might not seem of any particular interest. But for us, it’s different. Consider again 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 there – on a mote of dust suspended in a sunbeam.
