"Every atom in your body came from a star that exploded. And the atoms in your left hand probably came from a different star than your right hand. It is really the most poetic thing I know about physics. You are all stardust. You couldn’t be here if the stars hadn’t exploded because the elements - the carbon, nitrogen, oxygen, iron and all the things that matter for evolution and for life. They weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way for them to get into your body is if those stars were kind enough to explode. So forget what you know about religion. The stars died so that you could be here today."
