Remember the essential, the incontrovertible elements of the problem:
1. Great heat.
2. A sudden catastrophe.
3. Great evaporation of the seas and waters.
4. Great clouds.
5. An age of floods and snows and ice and torrents.
6. The human legends.
Find a theory that explains and embraces all these elements, and then, and not until then, throw mine aside.
Another will say:
"But in one place you give us legends about an age of dreadful and long-continued heat, as in the Arabian tale, where no rain is said to have fallen for seven years; and in another place you tell us of a period of constant rains and snows and cold. Are not these statements incompatible?"
