I thought that Dr Ballard was surveying the Black Sea for evidence of the "Biblical Flood". He has reported a submerged coastline many miles to sea from the current shore and the surmise is that when the Ice Age ended the glaciers melted and the sea level rose to current levels. In the course of this melt the Med was refilled and the Bosphorous was a waterfall filling the Black Sea to its current level with all those old seacoast cities being inundated.
Was there an Ark? Since Mount Ararat is just to the East of the Black Sea and various reports of the Ark have been made, then maybe there was a flood but no BRAIN FART!
