“Ancient people must have had huge lungs to live in such cities, or gills.”
During the last full-blown ice age the seas were much lower - some say 400’ lower. Our ancestors went through some serious climate change caused by the natural wobble of our planet.
That blows my theory ‘out of the water’, so to speak.
We now see the effects of going wobbly. 😐

The climate change that they went through was much more likely caused by a comet or asteroid impact. Check out the Younger Dryas cometary impact theory, it occurred roughly 11,600 years ago which, perhaps not so coincidentally, almost exactly matches what Egyptian priests supposedly told the Greek philosopher Solon, which was passed on to Plato over the ensuing 300 years, who in turn wrote the story of an advanced civilization that existed at that point distant point in time (Atlantis). I honestly don’t know if there was an advanced civilization or not, though I am open minded about the subject, but the coincidence of the information that Solon received some 2600 years ago with the evidence of cometary impacts all over North America that were not discovered or recognized until very recently, is hard to ignore.
