Best atheist one-liner

What's your favorite one-liner by an atheist? I'm torn between two.

Richard Dawkins reportedly said that if you believe the Earth is only 6,000 years old, then you believe that the Earth was created after the domestication of the dog. I love that remark but can't find a link to Dawkins saying such a thing. However, Wikipedia extends the idea:

To put this in perspective, those with the YEC worldview believe the world was created after the first domestication of the dog (and possibly the goat), after the first stones were laid at Stonehenge, after people settled in Scotland and more.

But as far as an actual one-liner, I guess I'd have to vote for George Carlin. He said this during a performance:

"If there is a god, may he strike this audience dead!" (More here.)

Dawkins, dissing Perry, speaks of evolution's beauty

I'm sure readers are aware that Rick Perry (and every other Republican nitwit running for president, other than Huntsman) said he doesn't believe in evolution. It's amazing that anyone in the civilized world could say such a thing in 2011, but there you go. The Republican field is composed of dimwits.

In an article today on PZ Myers' blog, he quotes Richard Dawkins' response to these Republican nitwits who fail to grasp that evolution is a fact of life on Earth (and everywhere else, for that matter; evolution rules the universe). Dawkins spoke about the exquisite beauty of evolution and the ineffable sadness of human beings who fail to understand this essential theory:

[Evolution is] one of the most beautiful ideas anyone ever had as well as arguably the most powerful. To die in ignorance of its elegance, and power to explain our own existence, is a tragic loss, comparable to dying without ever having experienced great music, great literature, or a beautiful sunset.

There's a lot more at PZ's post. Go read it. It's good stuff.
