This story has already been done on Discovery channel. They have already found several sites under the water. The problem I see is it doesn't PROVE anything. The Bible Noah flood was a GLOBAL flood. He believes it was a local flood. He has a theory and is skewing the evidence to suport what he believes. There are many flood evidences all over the world. Why would you limit it to the Black Sea in one time period? Science claims it took millions of years to form the Grand Canyon, but how long would it take if an earthen dam broke in Utah draining what was a great lake in a few days or weeks? He is using that theory. He says there was a large inland lake and a dam burst flooding the countryside.
Scientists are excavating in the Dead Sea and finding evidence of Sodom, just where the Bible said to look and dated to the same period, yet people still insist Sodom was a myth and the story an allegory. Course, if you ever admit that the Bible might be true, then you might have to repent, and we know, we can't expect that.
I used "you" in the general sense, not refering to you.
