Ok, first off I want to say that I believe the Biblical account of the flood and Noah's ark.  But I am dubious of some of the things on that site. For instance there is no mention of anchor stones in the Bible, so we don't know if there were such stones or not. Also not all of the prophecies of the Bible have come true, yet. The prophecies in the Book of Revelation are yet future. But all of the prophecies about Christ have come true. I believe there are over 300 of those.
