Lawrence Krauss

"Every atom in your body came f rom a star that exploded. And the atoms in your le f t hand probably came f rom a d i fferent star than your r ight hand. I t rea l ly is the most poet ic th ing I know about phys ics.You are al l stardust.You couldn't be here i f stars hadn't exp loded. Because the e lements , the carbon, n i t rogen, oxygen, i ron, a l l t h e t h i n g s t h a t m a t t e r f o r evo lu t i on weren ' t c rea ted a t the b e g i n n i n g o f t i m e . T h e y w e r e created in the nuclear furnaces of stars . And the only way they could get into your body is i f the stars were k ind enough to explode.So forget Jesus. The stars died so you could be here today."
