I'm saying God said that the water came from the sky and the ground and was not just created out of nowhere. Since we're told this, we can think about where that much water might be and how we might get that big a flood. Mud mentioned earlier:
As I said, no one has proposed a global flood model that explains the geographic evidence.
We can estimate the result of an event like this from our knowledge of modern earthquakes. From what we know about earthquakes, it looks like tectonic activity like that would be fatal to all life.Is anyone here familiar with Dr. John Baumgardner’s flood mechanism theory? He calls it Catastrophic Plate Tectonics which postulates that all the continents were together in a single land mass prior to the flood and that the tectonic plates began to separate quickly and catastrophically at the time of the Flood when the “fountains of the great deep burst forth.” The model has terrific explanatory power as to where all the water came from and went to, mountain building, erosive patterns, magmatic extrusions, geomagnetic pole reversals, post-flood ice-age, and others.
As I said, no one has proposed a global flood model that explains the geographic evidence.
