Here again is what I am saying: scientists seem to agree (correct me if I'm wrong) that massive flooding (or floods) have happened on the earth. According to the article in the Guardian, this is what it says: "The Black Sea was once a freshwater lake, well below sea level. About 7,000 years ago, according to geological evidence, the rising Mediterranean sea pushed a channel through what is now the Bosphorus, and then seawater poured in at about 200 times the volume of Niagara Falls. The Black Sea would have widened at the rate of a mile a day, submerging the original shoreline under hundreds of feet of salty water." This is not about estimates of when it happened, but rather the earth or great portions of the earth have been flooded many times. Do you agree with that premise, that great portions of the earth have been flooded many times causing the topography to change and civilizations to go underwater (drown, in effect)?
So apparently the scientists conclude that massive flooding by the Black Sea happened about 7,000 years ago, not when the flood of Noah's time as described in the Bible. But they do agree that massive floods changed a few things on the earth. And right now that is what I'm seeing from the article, whether or not they have the dating correct. The topography shows that something big happened. Scientists believe it happened about 7,000 years ago. Perhaps they'll change their minds about the timing, science is science. But, as Dr. Ballard said, what he saw he saw. Underwater. (I didn't entitle the article quoted...btw.)
