There is good geologic evidence to support the flooding. Paleoclimate is the study of the Earth's climate over geologic time (my degree was in geophysics).

Temperature data over hundreds of millions of years comes from isotope ratios in fossilized shells, and on a shorter timeframe of hundreds of thousands of years from isotope ratios in ice from glaciers (Greenland and Antarctica).

The Earth is currently in an icehouse climate overall, but in a short period of warm temperatures called an interglacial.

Interglacials are geologically brief periods of warm temperatures, about halfway between the extremes of hothouse and icehouse. They last anywhere from 10,000 to 15,000 years on average. We are currently in the latter part of an interglacial that began approx. 11,000 years ago. The name of our current interglacial is the Holocene.

During the ice age, ocean levels were about 400 feet lower than they are currently due to all the water locked up in continental ice sheets. The ice of the continental ice sheets melt during the warm interglacials, and ocean levels rise as a result. This is the source of the flooding people are talking about.

As one example, during the ice age, the area that is now the south china sea was one of the best places on Earth to live, but is now under 150 feet of water (which would have been 250 feet above sea level during the ice age). That entire subcontinent flooded and became a shallow sea.

Bottom line: the stories about flooding are real, and occurred roughly 11,000 years ago at the start of our current interglacial. Sea levels rose 400 feet globally during this period due to the melting of the continental ice sheets.

During the ice age, ocean levels were about 400 feet lower than they are currently due to all the water locked up in continental ice sheets.

Interglacials warm up rapidly over hundreds of years, and cool down slowly over thousands of years. The ice of the continental ice sheets melt during the warming, and ocean levels rise as a result. This is the source of the flooding people are talking about.

Humans are thought to have existed on Earth for several hundred thousand years, and therefore lived during the last ice age. During the ice age, ocean levels were about 400 feet lower than they are currently due to all the water locked up in continental ice sheets.
