In one Snooker admitted to the frailty of his beliefs which I reckon took some doing. However, Snooks you talk of mental giants befor you; I think you sell yourself short, you are clearly an intelligent individual.
As for the ice age and the bospherous theory these events occured long befor the episode in the bible is timed. At the time of the ice age certainly large tracts of water gravitated to the poles; the north sea was a lush meadow in the summer where mammoths grazed and a frozen waste in the winter. Nobody was into making boats back then (neanderthals' still existed). As for the potential opening of the Black Sea, certainly well befor biblical times.
