The water for the Flood came mostly from the "fountains of the deep." Where is this water now? A globe of the earth will show that the earth's surface is 2/3rds water, with the average height of land less than 5000 feet. The ocean basins, on the other hand, are on the average 12,000 feet deep. If one were to bulldoze the present land surface into the oceans so that the earth was absolutely level everywhere, at least a mile of water would cover everything. A number of scientists believe there was much more water in the earth's upper atmosphere prior to the Flood, producing a uniform, sub-tropical climate everywhere with almost no seasonal changes, violent storms or even regular rain and snowfall. It is has been suggested that the surface barometric pressure before the Flood may have been twice as high as it is now.
