@edgarblythe,
That's a nice
fantasy there.
But they don't write stories on localized floods. And the Great Flood is said to have flooded the whole world and told by not just the Jews, but the Mesopotamians (believed to be the first). But lest you think, "Ahhhh that's it, the Jews are plagiarists who borrowed culture from Egyptians and Mesopotamians," there is something else happening here.
https://en.m.wikipedia.org/wiki/Flood_myth
You see, the 6th century BC Genesis myth might have roots in that the Mesopotamians have a flood myth from 7th century BC Epic of Gilgamesh which in turn was probably recopied from 18th century BC. Let's set this tentatively at the 18th century BC, and say that it was recopied for posterity. But we also have a 6th century BC Hindu myth (this is not the first parallel that Jewish culture has with Hindu, around 2000BC, there is the famine with Joseph at the same time as a Brahmastra legend... hold on, Wikipedia made a screwy mistake. They say that the flood myth is 6th century BC, but Joseph's famine is after this, but dated before... the date set on that famine is somewhere around 2000BC; this is probably revisionism meant to fit this all into the Muslim calendar, that restricts events from being before 6000BC (when they believe the world was created). This is the Biblical timeline...

and it places the time of Noah at before 3000BC, so the Mesopotamian myth most either have been written before that, or this is a later account of an earlier event). Back to the flood. Regardless of the timeline (which I've said appears screwed up), there is in addition to this Chinese mythology, Greek, Norse, Muslim, Irish, Polynesian (it seems to skip Japan), Mesoamerican, Native American, and parts of Africa, South America, and Australia. Much of the world has this myth. So uhhhhh fantasy? You're the one living in a fantasy, something here definitely happened. And the Sphinx has water lines, suggesting human history is far older than we are told, that it preexisted the some sort of level rise which... is dated just before 3000BC.

The Great Flood actually happened, in addition to the Silurian period, there was probably an extinction level event, either as a result of melting icecaps or continental shift. Only certain people survived, probably from living on higher ground or making some sturdy boats.
But things get weirder. I've heard at least one hypothesis that suggests that the Great Flood story is actually a coded myth about a mass exodus from another planet. I don't care if you believe this or not, but there seems to be an asteroid belt just outside Mars, and the surface of Mars has some signs of previous life and some water. The hypothesis goes that there used to be a planet near where those asteroids are, and it got hit by a giant meteor (or in stranger stories, some weapon). The explosion fried the nearby planet Mars.

The original planet was called Phaeton

Basically, turning the life on a starship into life on a more relatable boat.
Are we are talking about genetic memory of sea life? Or we are talking about an exodus from a single island like Atlantis or Pangaea, and all the cultures that have this myth were once one culture? Or are we talking about exodus from another planet, where asteroids now are?
You can chose whichever one seems most plausible to you, but since a huge stretch of land has this myth, and much of it is not related by close borders, outright calling it a fantasy starts to sound like Scully making far more unbelievable denials than simply accepting the event.
