Some of the technical literature put forth by uniformitarian climatologists and archaeologists about the “African Aqualithic Period” (plentiful rivers and lakes where today is the Sahara Desert) report that the region became desert circa 1000 b. c., about 500 years after forty to fifty inches of rain had fallen per year, yet those same uniformitarians will tell you that the Ice Age ended circa 10000 b. c.; go figure!
