The Sidonians of ancient Canaan were great seafarers, based from their now-submerged port city (just offshore present day Zidon, Lebanon), they navigated all over the globe during the Ice Age, until the sea level rose to consume their preeminent port city, Sidon, and also the canaanite port city, Yarmuta, and the hittite port city Byblos, when then, after the sea level had risen because of the end of the Ice Age, which consumed hundreds of port cities worldwide (about two hundred in the Mediterranean and eastern Atlantic), the city of Tyre was built on an island, just offshore Lebanon, which therefore was a coastal hill during the Ice Age, until the sea level rose circa 1500 B.C.
Note that the more ancient navigating Canaanites were known as Sidonians, because Sidon was a son of Canaan in the Bible (Genesis 10), but later in the Bible, after the Exodus, when the Holy Land (much of Canaan) had been overtaken by the Hebrews out of Egypt, then Tyre, not Sidon, was the dominant port city of the phoenician Canaanites, because of the coastline change with the end of the Ice Age; that ending date, 1500 B.C., certainly ruffling the feathers of mainstream scientists, but nevertheless, conforming with the submerged ruin evidence.
Sidon was the Posidon of Plato’s Atlantis story, whose son Mneseus, was known also as Menestheo, looking much like king Menes of old kingdom Egypt, who united the upper and lower portions of the kingdom, the lower portion having been the Nile delta, so king Menes could well have been the Mnseseus of Plato’s account, having controlled the now submerged port cities of Menouthis and Heraklion, submerged in the Mediterranean near Alexandria, which was built by Alexander the Great because when he arrived, those two port cities of Menouthis/Menes and Heraklion/Nimrod had been submerged for over a thousand years, ancient history by Alexander’s time.
It has been a great mystery to mainstream scientists considering how the precise dimensions and alignment to true north (achieved only by timekeeping) of Egypt’s Great Pyramid of Giza was done, but after you read article #2 at http://IceAgeCivilizations.com, you can see that their perplexity is misplaced, for there is the answer, by the rate of the slow wobble of the earth’s axis, 72 years/degree, which enable them to utilize hexagon geometry (meaning earth measure), the same method utilized by the Sidonians and the Tyrians, the Phoenicians of Caanan, som of whom helped found Atlantis in the region of Gibraltar (the Pillars of Hercules/Nimrod).
