I think Gervais was just being facetious. Basicly he's saying what were saying. If Dinosaurs were gone before The Bible was written, then how can the creation story be accuarate.

Meaning they wrote it, when they wrote it, with no knowledge of how the world evolved or came to be.

The Bible doesnt mention dogs either, but they were around.

Its very simple to see that the people who wrote the Bible could only write from what they knew. Perhaps it was God inspired, and made sense to many people during THAT time period, and was never meant to be read thousands of years later by more intelligent and educated people.

The whole thing is enough to give one a headache. Why doesnt God just show up today. End all the speculation. Its like a thousand year drama playing out, and we die never seeing it. A bit like how well never know if there is life in outer space.

Also not mentioned in the Bible, and they couldnt even dream of the idea of going to the moon. But GOD would know.
