Well, If the Ark is ever found on Mount Arafat, I have an explanation.
During the Ice Age, the Mediterranean was isolated from the world's oceans ( I have a map that shows it in three different sections) and it partially dried out, after a point, the water level stabilized at a much reduced level and stayed that way for thousands of years.
Then the 'plug' at Gilbralter broke and the Mediterranean began to flood creating many refugees...and the same would occur in the Mediterranean as each of the three seperations were breached. Refugees were streaming everywhere with stories about flooding and everyone was convinced that the whole world was flooding.
Noah heard these stories and not knowing how much time he had to build the Ark, built it up on the heights of Mt. Ararat. The plug at the Black Sea broke, convincing everyone that Noah had been warned by God. If the Ark is ever found, it will be found on Mt. Arafat where Noah built it.
