It seems fairly clear that the story of Noah’s Ark evolved from the Epic of Gilgamesh, with changes made to accommodate the different faith of its authors. But what was the Epic of Gilgamesh based on? Quite possibly a real flood. Recent discoveries made in 1993 on the voyage taken by the Aquanaut offer fairly concrete evidence of a flood, in the Black Sea, which would have taken place at about the time as the time indicated in the Epic of Gilgamesh. The aquanaut, a vessel being shared by a Russian team searching the Black Sea for fallout and an American team searching for the evidence of a flood, employed the a CHIRP (an echo-locator) and a coring pipe to gather information and even samples of the sediments at the bottom of the lake and their contents. Evidence all pointed to a flood. The echo-locator showed evidence that the basin of the Black Sea was originally exposed erosion from wind and streams, but was suddenly thoroughly covered by a uniform layer of sediment. This is best explained if there indeed was a rapid rise in sea level. The data retrieved by coring also supported this idea. Coring involved the obtaining of samples of up to three meters of sediments from the bottom of the sea, which could then be observed and evaluated. At the base of the sea, the same signs were present of land that was at one time exposed to air, including some phenomena only present in dry conditions, like cracked mud. Directly above this was evidence of some freshwater life. However, a little higher in the sediment, there was a sudden appearance of salt water creatures, including snails which came from the Mediterranean . Above this there was continued evidence of a sudden rise in water level, and the entry of salt water into the previously mostly empty basin. The flood waters would have come from an overflowing Mediterranean Sea, which would have been bloated by the flooding of the Atlantic which was in turn caused by the melting of the great glaciers from the previous ice age. The sudden breakdown of the land separating the Mediterranean from the Black Sea would have caused rapid flooding, the likes of which were unheard of in a majority of the world (Water would have been cascading in with the 200 times the force of Niagara Falls!). This flood would have had serious impacts on its witnesses, and the severity and unpredictability of the flood would have made it an occurrence outstanding of all others.
