When the Exodus of the Hebrews out-of-Egypt happened circa 1450 b. c., they ventured eastward from the (now extinct) Pelusaic distributary of the Nile river delta down the Wadi Tumilat, then a slow moving navigable stream, to the Bitter Lakes region of the Sinai (named for Canaan’s son Sin) then northward, yet had they continued down the Wadi Tumilat, they would have come to a gulf of the Indian Ocean, the Red Sea (not the reed sea where the Hebrews saw its parting by the night-long gale from the east).
During the Ice Age, the Nile flowed much broader and deeper for all that water to have spilled out even eastward then southward to the the southern ocean, the Red Sea (red anciently meant southern and the Black Sea to the north), because much more rain fell all across the Middle East and North Africa until the time of the Exodus when the world ocean had cooled to about today’s temperatures for the dense cloud cover of the Ice Age to have ceased.
Upon entrance into the Promised Land circa 1400 b. c., Joshua (Yehoshua) who led the Israelites found the land becoming barren by rainfall lack (particularly in the lowlands), yet by the time of kings David and Solomon, sophisticated cistern drip irrigation systems had been excavated and channeled such that Solomon became known as the richest man in the world, in no small part of course because he traded as widely as Tarshish (post ice age Atlantis) and Ophir of Malacca, his passage to Ophir though from the gulf of Aqaba not up the Nile then east down the Wadi Tumilat, by then dry as a bone.
Having preceded the Exodus by about nine hundred years, the warmer ocean (average temp not 50 degrees F. rather 80) after Noah’s Flood was the engine for the Ice Age (having caused the evaporation necessary for expansive ice age cloud cover), later of course it cooled to about today’s temperatures by the time of the Exodus when the sea level rose while the deserts of the world began. Submerged ruins are found off the Holy Land from canaanite days, and in Aboukir bay of Egypt (near Alexandria), as well as dozens of other locations worldwide, this subject extremely taboo to mainstream scientists because of the damage it does to their timeline for the end of the Ice Age.
Predictably the ruins of hundreds of ancient settlements and even cities have been discovered in the vast deserts of the world, such as the Great Indian Desert (of the Indus Valley Civilization), the desert of southern Iraq (the Sumerians), the Sahara (Libyans and Egyptians), the Negev desert of southern Israel (Canaanites), and the Takla Makan desert of western China (Tocharians of Togarmah, a grandson of Japheth), regions abandoned beginning circa 1500 b. c. when the rainfall began to drastically decline because the ocean had cooled to about today’s temperatures, the end of the Ice Age.
So probably deliberate ignorance is the reason today’s manmade climate change alarmists seldomly mention the hydrologic cycle, because any atmospheric warming (by any temporary increase of solar output) is mitigated by the greater cloud cover it produces, by more evaporation off the ocean, this the negative feedback mechanism in the hydrologic cycle ignored by uniformitarian propagandists because the logic following is that the Ice Age must have been caused by the ocean warmer having been heated from below by the fountains of the deep for Noah’s Flood.
