"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 the atoms in your right hand. It really is the most poetic thing I know about the universe: we are all stardust. You wouldn’t be here if stars hadn’t exploded because the elements (the carbon, nitrogen, oxygen, all the things that matter for evolution) weren’t created at the beginning of time, they were created in stars. So forget Jesus. Stars died so you could live."
