While googling “submerged ruins Greece,” I ran across a report at the website of a yacht charter outfit in the Sporades Islands, in the Aegean Sea, that there is a submerged city, the ruins found off the northern coast of the island of Psathoura, the city built of stone blocks, so why is National Geographic not all over that with underwater film crews? And there are other submerged ruins’ sites off Abdera, Samothrace, and Lemnos, and Elafonisos too, all submerged since the end of the Ice Age, which began to end circa 1500 B.C., explaining the presence of “bronze age” ruins on the shallow seafloor, in many locations throughout the Mediterranean and elsewhere including many off India.
One of the islands of the Sporades is Pelagos, the namesake of the biblical character Peleg, five generations before Abraham, who navigated and built along the shores of the ice age Mediterranean, when sea level was a few hundred feet lower, and thereafter, so many stone ruins were submerged and then discovered on the shallow seafloor in modern times, which nevertheless are all but ignored by mainstream scientists, because they say the Ice Age ended circa 10000 B.C., which clearly does not conform to this evidence from the biblical template.
The ancient people of Crimea, the Cimmerians, had a legend that the Black Sea was infilled by the ocean (when it rose with the end of the Ice Age) in the time of Dardan, the same as king Dardanus of greek lore, commonly thought to have lived circa 1500 B.C., when the Ice Age ended. The name Cimmer is Gimmira, Gomer, a son of Japheth in the Bible, whose tribes were living around the old black sea lake before the sea level rose to infill its basin and increase its area by 40%, within several decades, explained as you read on here under category Black Sea Research, to see that the evidence about the Ice Age actually confirms the Genesis model, see http://genesisveracityfoundation.com.
