Naturalists create such a fuss over creationist theories about ancient geological history, often concluding they are contradictory and illogical. Granted every proposed model for creation or for the Genesis Flood by a creationist scientist cannot be true, because some of their models would contradict that of their own Christian colleagues. We are all trying to put meat on the bones of Genesis, and everything that is suggested doesn’t fit properly for all circumstances. Yet, this is to be expected, if we are seeking the truth about a singularity in the past that cannot be repeated today. The very same would be true of models presented by naturalist scientists. Everything they put forth cannot be true concerning the beginning of the universe, because some of their models contradict other naturalist models. Even the Big Bang theory is not universally accepted among scientists who don’t believe in God.
So, what about all the fuss over the waters of the Noahic Flood, where did it come from and where did it go? I already wrote a blog-post about the origin of the waters, so in this posting I intend to place more emphasis upon where the flood water went after it covered all the mountains (high hills) of the earth.
Actually, evolutionists, themselves, provide a very reasonable model for where the flood waters went. Of course the time factor would be different in a creationist/Genesis Flood model, but such differences in worldview would be expected. Both creationists and evolutionists agree that, at one time in our ancient history, all the present continents were connected in one giant continent, the southern part of which some call Gondwana. How large this great continent was, we cannot say. Did it include only the existing continents, or was there even more landmass in existence at that time? One can only imagine, but there is evidence it may have been larger. In any event, geologist, Dr. Terence McCarthy, and paleontologist, Dr. Bruce Rubridge, offer us a hint of how things may have occurred as the African continent emerged from the flood waters in their recent book, which speaks of the birth of the Indian and Atlantic oceans:
The break-up of Gondwana began with the opening of the Indian Ocean along the African east coast, heralded by the eruption of basalts and rhyolites of the Lebombo region… Some 120 million years ago, South America began to detach from Africa, opening rifts along the southern African west coast. This thinned the continental crust: the start of the Atlantic Ocean.
As I claimed above, creationists would dispute the 120 million year timeframe, which corresponds to the naturalist’s theory of uniformitarianism, but there can be little doubt that McCarthy and Rubridge describe a very plausible argument for where the waters of the Genesis flood went.
About 70 % of the earth’s surface is presently covered by water, but this may have been a lot less in the pre-flood world. Much of the present water may have come from under the earth’s crust. Nevertheless, the deep oceans of today hold the waters of the Noahic Flood of thousands of years ago. If the high mountains of today, like Mt. Everest, were shaved off (so people could actually live on and farm the **mountains**) and the deep crevices of the ocean floor were smoothed out, the oceans would again overflow their banks and cover the earth to about the depth described in Genesis 7; and if one smoothed all the dry land to sea level and also smoothed out the ocean floor, the entire globe would be covered by water up to nearly two miles above what was once dry land.
The problem is, the critics like to begin with a post-flood world, using post-flood topography, and ask: where did all the **additional** water come from to flood the entire earth, and where did all this **additional** water go? The answer to these questions lies in the operation of tectonics and hydraulics. If the earth’s crust from beneath the ocean floor pushes upward, the water must go somewhere. It flooded the ancient Pangaea world. Afterward, the ocean floor deepened, driving landmass higher on the large continent and eventually breaking it up over the next few centuries into smaller continents. The flood waters flowed off the huge continent into the deepening valley of the ocean floor. Eventually, the continent broke up over the next few centuries into what we find today. Some landmass was certainly lost to a larger and deeper ocean floor.
 In the pre-flood world there were no mountains like Mt. Everest or Mt. McKinley. The Lord made the earth to dwell in (Isaiah 45:18) even the mountains, like Mt. Zion, were meant to dwell upon, or at least could be farmed etc.
