The two floods scientifically hypothised are the Black Sea (around 7,600 years ago) and the Caspian and Black Seas (around 16,000 years ago) - Outburst flood - Wikipedia, the free encyclopedia. None of them could have destroyed all human population on Earth. Red Sea floods happened approximately between 69,000 and 77,000 years ago. I do not think the memory of that would have survived.
Dear Aupmanyav, False, since Isaiah tells us that Adam's world, the first Heaven, was clean dissolved in the Flood Isa 24:19 along with every creature that breathed. Gen 6:17 The Bible does NOT say that our world was destroyed in the Flood because it wasn't and couldn't be dissolved in water, since our Earth is a Rock. Try again? God Bless you.
In Love,
Aman
