"The belief that dinosaurs are only 3000 years old and that the universe is only 6000 years old... How to give an idea of the real timespan of the world. One way to put it which I've recently been thinking about is that if somebody believes that the world is only 6000 years old (or of the order of a few thousand years old) when the true age of the Earth is of the order of a few -billion- years old, that means they're out by a factor of... a million. Um, which is not a trivial error.
It's... I'm not very good at arithematic, and I calculated that it's equivalent to believing that the distance from New York to San Francisco is 700 yards. But I've recieved a letter from a mathematician who've done this - done this sum again. And he said I got it wrong, it's actually equivalent to believing that the distance from New York to San Francisco is 28 -feet-."
Richard Dawkins FTW.
