FYI, there is a tradition in the Midrash that there were many floods:
“The deluge in the time of Noah was by no means the only flood with which this earth was visited. The first flood did its work of destruction as far as Jaffé, and the one of Noah’s days extended to Barbary.”

Notice that Peter also refers to it this way: "KJV" [2 Peter 3:5-7] For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water: Whereby the world that then was, being overflowed with water, perished: But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.
It definitely appears that Peter is speaking of a different time.....before the creation of Genesis.
The prior floods did not happen in the “ice age” of the scientists but from the days of ‘Enosh onward.
