Penn Jillette said this quote

Nobody that has seen a baby born can believe in god for a second. When you see your child born, and the panic, and the amount of technology that is saving the life of the two people you love most in the world, when you see how much stainless steel and money it takes to fight off the fact that god wants both those people dead, no one, no one can look into the eyes of a newborn baby and say there's a god, because I'll tell ya, if we were squatting in the woods, the two people I love most would be dead. There's just no way around that. If I were in charge, no way. We need technology to fight against nature; nature so wants us dead. Nature is trying to kill us.
