Oh, my, so many interesting points in the following article:
Megafloods of the Ice Age | NOVA | PBS
That's great, YoursTrue.
First, you were claiming that the Black Sea Deluge Hypothesis (proposed date of 5700 BCE) was associated with the Genesis Flood (supposedly 2300 BCE).
Now, You have posted a link to flood that it is not only, not about 10,000 years before the BSDH and about 12,500 years before the Genesis Flood, BUT also the Glacial Lake Missoula is not in the same continent as the Noah's Flood.
And you are forgetting the story about Noah, is that rain for 40 days and 40 nights, but the Missoula Flood occurred due to ice collapsing that dammed the Lake, causing localised destruction in areas with no evidence of human death, because it pre-dated Clovis culture in North America, in which earlier Americans arrived in the continent.
You are comparing one example after another, which bear no relations to the Genesis Flood. This don't help your argument that support Genesis Flood, not only in timings, but also locations.
These are false equivalence fallacy.
If you were comparing a more recent flooding close to 2300 BCE, you might have a case, which you don't...not at Mesopotamia and certainly not near Ararat.
