When Adam and Eve died, Satan introduced the theory of evilution into the world that teaches that man and animals are genetically related. He downplayed the story of the creation and fall of man by the sin of Adam and Eve. Then women began to assume a dominant role in human affairs. Satan downplayed the command of God that women were to be in subjection to their husbands.
These fallen angels must have introduced their scheme as an evolutionary advance for mankind. They promised the women that if they married and bore their offspring they would not have to be in subjection to their husbands. As a result, the world was overrun by half human half animal genetic monstrosities and God decided to destroy the entire world except for Noah and his family.
The pre-Flood world was a zoological nightmare. From left to right, a grypon, a manticore, a ferocious human-headed carnivore with 3 interlocking rows of teeth, a basilick, a unicorn, an Assyrian human headed winged bull.
I think I dated one of those once.
