Seems to me the pyramids pose a problem when considering the flood.
If they were built before the flood, there would be much evidence inside the structures. The great pressure of several thousand feet of water would force water through any little crack or seam, into the structure and when the flood waters receded, would remain there for many many years, if not forever, as there'd be no pressure to force the water back out. Certainly there'd be 'bathtub rings' plainly visible even today.
If they were built shortly after the flood, who would have done the building? There are over a hundred pyramids throughout Egypt, each requiring thousands of man-years to complete. Even if Noah and family reproduced like bunnies, and they all moved to Egypt and worked only on building pyramids, they couldn't have gotten the job done within certainly a very many centuries.
So which is it?
Before the flood with no evidence that the insides were ever wet;
or after the flood, when there was no labor to complete the task.
Just curious as to a 'logical' answer.
The Bible has to be true - no one could make all that up.
