I would assume that a single geophysicist knows his stuff less than the thousands of geophysicists, geologists, paleontologists, archaeologists and anthropologists who disagree with him, but maybe that's just me.
Could be just you.
Such reasoning backfires when you consider that Darwin himself challenged the current theories of his day, or Galileo, and so on and so forth....the majority is not always right.
A few questions:
- you spoke about the topology of the Earth changing as a result of the Flood. What do they suggest the topology of the Earth was before the Flood? What mechanism do they suggest that led to the topology we see today?
If I remember correctly, it is simply proposed that before the Flood there were only "high hills," but no true mountains, as we know them today. The mechanism suggested for forming today's topography is beyond my ability to explain, so I'll simply refer this bit to you, from the site of the geophysicist Dr. John Baumgardner:
My conclusion is that the Flood was one facet of a larger global-scale tectonic cataclysm. A key aspect of this catastrophe was the rapid sinking, in conveyor belt fashion, of the pre-Flood ocean tectonic plates into the earth's interior. The energy required for the process was derived from the earth's gravity acting on the excess weight of these cold ocean plates relative to the hotter and less dense mantle rock into which they slid. Decades of laboratory experiments attest to the fact that, under stress, mantle rock, at temperatures estimated for the earth's interior, can weaken by factors of billions or more. My work on this problem has primarily involved computer experiments that apply the properties of silicate rock, as measured in these laboratory experiments, to the setting of the earth's mantle. These calculations demonstrate that a catastrophic instability can indeed occur in a planet with the size and structure of the earth. This mechanism for the Flood cataclysm has become known as catastrophic plate tectonics
- the diameter of the Earth at the equator is 12,756.32 km. The diameter at the poles is slightly less: 12,715.43 km. If you were to assume that the Earth was a perfect sphere with the smaller diameter, it would still take 15,238,256 cubic kilometers of water to cover the surface to a depth of 3 meters (assumed arbitrarily but conservatively as the minimum depth that would kill all tall animals). Even for this lower limit, that's too much water to just come from aquifers. Where did all the water come from, and where did it go?
There was rain in addition to what came from the ground. This must also be taken into consideration.
