Isn't it funny how plate tectonics is now the answer for everything when earlier in my own life Wegener was hooted out of geological assemblies for suggesting the earth had crustal plates?
You have forgotten some very salient facts, sir. Radioactive heating in the interior of the earth was precisely what caused the waters of Noah's Flood to be driven out of the serpentine and other original rocks, continue heating under increasing pressure, and finally explode upwards through the crust, initiating the Flood itself.
About half the oceans' waters were outgased at this time and the changes in the appearance of the earth incredible. There is NO WAY any part of the land that existed was not inundated and buried.
You claim an old age for the rocks. That is the result of radiometric dating. Radio decay was much faster in the past and the dates need to be corrected. This can be done via the redshift curve, and when this is done, we find that the three biblical catastrophes, the Deluge, Babel, and the time of Peleg, exactly match the breaks in the geologic record which take place all over the world.
You want to ignore science for your theory, the same way evolutionists do, picking and choosing exactly what facts you want to consider.
That is not good history or science. It is simply story-telling.
