Most people like Palin actually dont believe that dinosaurs really existed, since the bible doesn't mention them getting into Noah's Ark.
It's an interesting statement: "I think there's a really good chance Sarah Palin could become president, and I think that's a really scary thing... I think the pick was made for political purposes... Do the actuary tables and there's a one out of three chance, if not more, that McCain doesn't survive his first term and it'll be President Palin... It's like a really bad Disney movie. The hockey mom, you know, 'oh, I'm just a hockey mom'... and she's facing down President Putin... It's totally absurd... it's a really terrifying possibility... I need to know if she really think that dinosaurs were here 4,000 years ago. I want to know that, I really do. Because she's gonna have the nuclear codes. "
