The April 2008 edition of National Geographic has an article about life in the Sahel, the land running across the middle of Africa where the Sahara Desert of North Africa transitions into the forests and pastures of Central Africa. The author points out that Sahil (Sahel) is the ancient arabic word for shoreline, but then bizarrely guesses this meaning from that the Sahel ecological transition zone stretches across Africa, west to east, from the Atlantic shoreline to the Indian Ocean shoreline, failing to acknowledge that the ancient word sahil means what it says; there was a shoreline across central Africa during the Ice Age, when the Sahara was a series of huge lakes with interconnecting marshes and streams in the vast Sahara basins of Libya, Egypt, Sudan, Chad, Algeria, Mali, and Mauretania, on the southern edge of which the ancient cities of Gao and Timbuktu were built, now in desest desolation, because the climate dried out when the Ice Age ended circa 1500 B.C.
Ruins of megalithic bronze age cities, such as of the Kingdom of Yam in the libyan Sahara and of Kerma in the sudanese Sahara confirm that the Ice Age, bringing much more rainfall to Africa, was ongoing during the so-called Bronze Age in the 2000 B.C. timeframe, when the biggest pyramids of Egypt were being built, as well as, the great ziggarauts and cities of what are now the Iraqi and Iranian deserts of the Middle East. It must have been much wetter there then when those civilizations were flourishing, and that, because the Ice Age was ongoing, until about 1500 B.C., when the Ice Age cloudcover dissipated, and so the ice age icepacks melted, for sea level to rise a few hundred feet, consuming 25 million square miles of land, and many bronze age port cites in the process, within a century, see http://genesisveracityfoundation.com.
