Here is a clip of Christopher Hitchens in a debate with John Haldane. (~5 min)
I agree, the debate is over. Creationism has no validity. We are evolved creatures, and part of our evolution is a basic sense of morality. Not a moral absolute, of course, but even apes and dogs have been shown to have morals. We don't need god to be good. In fact, I'd say god makes it harder to be good for the right reason, especially since the god of Abraham is so amoral.
