As Plato clearly states in Critias and Timeaus, Atlantis was the dominant maritime power in the world during the bronze age, based in the Gibraltar region, whose coastal megalithic port cities succumbed to the sea when the Ice Age ended, with ruins of those cities now found submerged off Huelva, Rota, Chipiona, Cadiz, Zarahas do los Atunes Beach, Cueta, and Tarifa, Atlantis extended outside and inside the Pillars of Hercules (Gibraltar, which means fire altar), according to Plato, from the eastern Atlantic seaboard east to Italy and Libya, which included Sardinia, from where the Sea People invaded Egypt circa 1400 B.C., invading in 1,000 ships, defeated by the Egyptians under Ramses III, but the effect felt, as the mass migrations of people continued from the sea, and by land from Libya, which was drying at that time because of the end of the Ice Age.
Plato counted 9,000 solar cycles before Solon’s time back for the supposed 9600 B.C. date for the submergence of Atlantis, but the actual date was 9,000 lunar cycles before, putting the date at circa 1500 B.C., when the Exodus occurred too, and many coastal bronze age cities were submerged by the risen sea from the end of the Ice Age, when the Egyptian cites of Menouthis and Herakleion also succumbed to the sea, and cites also now submerged off Greece, at Platygiali, Astakos, Abdera, Samos and Elafonisos islands, and undoubtedly other locations, submerged to end the bronze age, when the climate also drastically dried out worldwide, causing the disasters in Egypt described in the Ipuwer Papyrus, which comports very nicely with the Exodus account in the Bible; the Ice Age’s causation and end explained cogently with the Global Flood Model, read more about it in the free ebook download of my first book, Old Earth? Why Not!
The “Shardana” were one of the tribes of the Sea People described in the Ramses III account of the war against the maritime invaders, commonly thought to have been the people of ancient Sardinia, who were part of the Atlantean Empire of the western Mediterranean, who did invade circa 1400 B.C. into Egypt, at the same time that the Temehu, the ancient stone masons of Libya, were migrating into Egypt because Libya was quickly becoming the desolate desert region of Sahara which it remains today, these migrations because of catastrophic climate change, vividly described in the Ipuwer Papyrus, and understandable according to the Global Flood Model, corroborating the Genesis account.
