As a Christian do you believe the Noah's Ark story to be literally true?

The Bible is full of stories which are not really true. Now we know that Adam & Eve are not the first people on Earth. The Noah's Arc story is not true. Just like Adam & Eve story it is a way of explaining things. Just like Pharaoh drowned in the sea after he and his soldiers went after Moses and his people. Have you ever read such incident in your History book?
