A question asked at Yahoo, a fantastic quote about heaven from Richard Dawkins, and Mr. Dawkins explains evidence for evolution from DNA sequencing in a 2 minute video.

"If you're an atheist, you believe this is the only life you're going to get. It's a precious life. It's a beautiful life. It's something that we should live to the full, to the end of our days. Whereas if you're religious and you believe there is another life somehow, that means you don't live this life to the full, because you think you're going to get another one—that's an awfully negative way to live a life. Being an atheist frees you up to live this life properly, happily, and fully."
-- Richard Dawkins
