Some require cool clear water, some need brackish water, some need ocean water, some need water even saltier. A flood would have destroyed at least some of these habitats. How did sensitive marine life such as coral survive?
Since most coral are found in shallow water, the turbidity created by the runoff from the land would effectively cut them off from the sun. The silt covering the reef after the rains were over would kill all the coral. By the way, the rates at which coral deposits calcium are well known, and some highly mature reefs (such a the great barrier) have been around for millions of years to be deposited to their observed thickness.
How did diseases survive? Many diseases can't survive in hosts other than humans. Many others can only survive in humans and in short-lived arthropod vectors.
The list includes typhus, measles, smallpox, polio, gonorrhea, syphilis. For these diseases to have survived the Flood, they must all have infected one or ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
