RL said..."It is commonly thought that all the continents were at one time united.
IF that were the case during the Flood, then obviously a much smaller amount of water would be required to cover 'all the earth' ( i.e. all the land , as the word could easily be translated

In addition
IFmany of the areas which at present are high mountain ranges were much lower, the same is true -- much less water required. And again, scientific evidence exists that many of the high mountains include large areas of sedimentary rock and even deposits of coral (as on Everest, the Earth's tallest mtn) They had to be low enough at some point in history to be underwater, whether that was during the Flood or even afterward. "...
The operative words in all this is "IF".
EVidence does not support RL's position, in fact, all the evidence refutes his "IFs"
RL's last statement assumes that all these oceanic deposits and fossils were deposited on the tops of present mountains. The evidence does not support this outrageous stamenet either. It strongly refutes it.
All this evidence does not exist in a vacuum. There is context from several disciplines that clearly show the SEQUENCE of deposition, movement, deformation and erosion. This is the kind of stuff that RL merrily ignores.
RL, please dont infer that geologists are fools like you, most are not. Those that believe as you are either employed by govt where they cant hurt anyone, or else they are involved in Creationist causes,(after theyve refuted most all their educational credentials. This they do for many reasons known only to them). Fortunately the number of Creationist Geologists is very small, small enough to be individual curiosities to those of us employed in the trenches of the science.
