You not only lack any understanding of basic physics, like buoyancy, but also the ability of logical thinking.<quoted text>The flood water seems to have drained primarily to the present ocean basins.
I shall teach you basic logic.
You cannot flood the earth using the water that already exists. If there is dry land anywhere, then that means you have to have additional water come from somewhere else. The entire reason that there is dry land is precisely because there isn't enough water to cover it up.
The amazing thing about sea level is that it is the lowest you can go and still be on the "surface". Water necessarily rushes downhill to the lowest level it can get: Sea level. Thus, dry land is necessarily above and beyond what the water >can< cover.
Hence, if the land was drowned during the flood, per definition the should have been water ADDED to the existing oceans. to cover the highest mountain, Everest, 2.5 times more water to be precisely.
When the flood receded, 2.5 times the current amount of water must drain or go somewhere.
I think I would already have understood this when I was a 12 year old boy or so.
