There is a possibility that a Planet X-type body might have brought on the deluge, as ancient records of both China and Egypt refer to an extremely large object in the sky that was prevalent for a time. Yet, according to this, research, in order to flood the entire planet, you would need 3.5 times the amount of water that’s currently on the surface. Mark Combs learned that there are enormous reservoirs of water inside the Earth, and some of this may have contributed to the Great Flood. He also compared Genesis with modern science, and noted that the idea of the Big Bang in which everything began all at once is similar to the initial creation as described in the Bible. Combs , an expert on the flood of Noah, cataclysmic destruction, and religions of the ancient world, discussed his investigation into the Great Flood, in which he drew correlations between history, science, and religion.
