Why did the dinosaurs go extinct? Answers in Genesis doesn't say, but the Creationist group is sure of one thing: the giant reptiles were on Noah's Ark.

In a 60-second radio ad released Monday, Answers in Genesis President Ken Ham lamented that dinosaurs had been used to "indoctrinate children" to believe in the theory of evolution.

He said dinosaurs could not have existed before humans because the Bible clear stated all land animals and humans were created on the same day "about 6,000 years ago."

There was nothing mysterious about dinosaurs for those who understood the Bible, Ham concluded.

But why were did dinosaurs go if they were created a mere 6,000 years ago? For that, you apparently have to visit the Creation Museum in Kentucky.
