BEFORE ATLANTIS
They knew about the seasons and were able to predict weather changes based on the movement of the stars and the shift of the earth's equator in relation to the sun. Although the Khoisan primarily lived in open camps along the riverside, they also used caves and rock formations for religious ceremonies and shamanic rituals. They were a peaceful people without chieftains or war-bands who instead lived in a matriarchal commune led by the tribal elders. They took only what they needed from the earth without wasting anything and lived in a rather utopian society who experienced peace and harmony in Africa for over 30,000 years. That is, until the Toba super-volcano erupted in Sumatra, almost 5,000-miles from their African homeland.
Ash filled the air as darkness covered the skies, blackening out the sun. As the smoke began to rise, acid rain began to pour down over the earth along with soot and hot magma. There was an earthquake followed by tidal waves, tsunamis, hurricanes and roaring seas. The northern and southern hemispheres were thrown into a freezing, relentless ice age while the Khoisan's homeland near the equator became a scorching desert in the midst of an arid dry spell. The eruption of the Toba super-volcano was so vast and so great, it almost annihilated the Khoisan people along with the entire animal kingdom. All of the remaining mega-reptiles that had survived since the time of the dinosaurs had now been wiped out completely and most of the older prehistoric hominids, giant sea monsters and land roaming flightless birds also went extinct. The time of the wholly mammoth and the great Old Ice Age mammals had arrived. Out of this destruction, only about 10,000 human beings survived.
With the fertile grasslands turning into dust and sand, the Khoisan were forced to leave the Horn of Africa by crossing the Bab-el-Mandeb strait between the Red Sea and the Gulf of Aden to the coast of Yemen in Saudi Arabia over 25-miles of waist deep trecherous water. There on the other side, they found lush vegetation and a myriad of newer animal species. Needless to say, the nomadic hunters and gatherers spread out over the face of the earth and never returned to South Africa, where they left their stonehenge-like monuments and rock carvings behind to be discovered several millennia later after they had already been forgotten. This was the beginning of the great human migration event out of Africa, when the Khoisan began exploring their world for the very first time.
