Myths can be useful, but as they don’t come with dates, it is unusual for them to be useful for dating catastrophic events.
In “Noah’s Flood”, Ryan and Pitman cite an ancient flood myth from the northern Aegean, then claim (without basis) that it must have originated from the Black Sea flood, and that the ancestors of the carriers of that myth had to move, wound up settling on the Aegean, subsequently (and most conveniently) forgetting where the event took place while still remembering the event in some detail.
Yes, the Pleistocene / Holocene boundary has been dated to about 10,500 years ago, IOW, not very far off the time Plato gave for the destruction of Atlantis, a myth that may have begun with Plato rather than having arrived in Greece via Solon’s supposed visit to Egypt.
Yes, it is widely accepted that large floods from glacial meltwater has happened a number of times in human times.
Science is a method, rather than being a body of knowledge. Knowledge increases, and comes from experience as well as the Aristotlian syllogism. Stuff that is disproved is discarded in favor of something else.
IOW, don’t project the acts and attitudes of people who reject the scientific method and the knowledge derived by it onto practitioners and students of the sciences.
The scientific community doesn’t have a trademark after it, but that did help set the tone for your old, tired tirade.
I won't bore you with the long list of "junk" science perpetrated under the aegis of government funding. You're familiar with it, or should be. As in the days of Galileo, government is now the church that persecutes those who practice real science outside the accepted paradigm or conventional wisdom. They're on their own while the faithful feed at the government trough. Do you disagree with that?
