Forget this nonsense and pick up a Bible. Noah's flood was a reality, and it covered the ENTIRE world, not just the Bosporus like this fairy tale tells us!
Now it becomes more apparent where the insanity of the Islamists comes from. Like you they claim to have their Gods ear and to know his heart. I seem to remember pride and arrogance being among the seven deadly sins. Surely one who claims to know Gods mind is arrogant indeed.
I'm not much for postulating or "explaining" the hows and whys of Biblical accounts, but I saw a documentary on asteroid collisions and the effects (I think it was mainly about the Shoemakers of Shoemaker-Levy comet fame). One of the things mentioned was that a mountain-sized asteroid striking an ocean would launch not only massive tidal waves, but would put unimaginable, countless tons of water, as vapor, into the atmosphere, which would immediately begin to be shed as rain over the earth, for untold days.
Such speculation got me thinking about Noah's flood, and the possibility that a massive asteroid impact put the vapor in the air, the shock wave broke up "the fountains of the deep", and the earth was knocked off its axis, and "seedtime and harvest, and cold and heat, and summer and winter" -- the seasons -- began.
