the following (Gen 7:11) describes a very different environment than the one they are currently observing :
on that day all the springs of the great deep burst forth,
Genesis 7:11...the same day were all the fountains of the great deep broken up, and the windows of heaven were opened.
In other words, the sources of the seawaters all of a sudden broke out and rose up as the sky poured forth torrents of rain.
It would have looked even worse for the people living in what is now the basin of the Black Sea, because the saltwaters of the Mediterranean Sea broke through the mountain passes above their heads at the Dardenelles Strait and poured down upon them as if the windows of heaven had been suddenly opened and the former lake flooded above everything they knew as their homes, hills, and mountains. The flooding would have naturally swept Noah’s Ark northeastwards to the mountains in the kingdom of Ararat.
