7 The lakes in the middle of the Sahara desert

Perhaps the best argument for the existence of an “Atlantis” is the fact that a civilization once existed which possessed certain technologies that were essentially impossible for them to have in terms of what we know today. I discuss these anomalies the Ancient Enigmas and Anomalies section on my website, including the pyramids of Giza, ancient stone cutting and drilling and the Nazca lines and Palpa mountains. A key argument is the issue of the weathering of the Sphinx, which could only have been caused by continual rainfall. The Sahara desert experienced high levels of rainfall 5,000 to 10,000 years ago, and

“a vast lake covered the region, and a whole network of lakes and Neolithic fishermen occupied the Sahara.” 47

These conclusions are based on eroding fragments of lake sediments found in the heart of the Sahara that contain the skeletons of fish and crocodile bones. Figure 21 (top, Mercator’s 1569 map) shows two huge lakes and numerous rivers in the middle of the Sahara desert. One of NASA satellite images of the Sahara desert (centre) shows what appears to be a lake corresponding to Mercator’s eastern lake (encircled), while it is absent on another (bottom). The lake on the centre map may have been due to flash rains or floods in the area (can anyone comment?), but it should be noted that there is a permanent group of lakes north west to the encircled lake, albeit smaller in size. This group of lakes, called the lakes of Ounianga in Chad, are sustained by underground aquifers and not rainfall. The lakes formed part of a much larger lake that existed during the “Green Sahara” period, estimated to have existed from 7500 – 3000 BCE.

The other lake on Mercator’s map is shown enlarged in Figure 22. This lake would have disappeared probably around 3000 BCE at the latest (5,000 years ago), if not millennia earlier. Mercator’s map is astonishingly accurate not only in terms of the location and relative size of the lake, but also the location of the rivers that fed it (coloured blue by me). All that remains today are dry riverbeds. Where did he get his information from? He most certainly must have had access to ancient maps. Who were these mapmakers? Neolithic humans who had only just mastered stone tools? These mapmakers would have possessed a method to record latitude and longitude, otherwise it would have been near impossible to map an entire continent.

It should be noted that Ortelius also shows lakes in the Sahara desert on his maps, in more or less the same locations. On his world map of 1570 there are only two main lakes, (Figure 23, top), while his more detailed map of Africa (Figure 23, bottom), shows many more lakes and rivers in the Sahara desert, as may be expected for the Green Sahara period. Where did he obtain this information from? Pure guesswork?
