"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; You are all stardust. You couldnt be here if stars hadn't exploded, because the elements that matter for evolution weren't created at the beginning of time, they were created in stars. Stars died so you could live."
