Archaeologists at the University of Cambridge found huge quantities of stone tools on the ground in Massak Settafet near Fezzan in southern Libya . They discovered an average of 75 tools in every square meter of ground . Tools are believed to have been made 500,000 years ago in the area . Scientists say it could be the earliest example of a human - made landscape . Pits and holes left by piles of stone helped attract animals to the area . The researchers estimate that early human activity would have left behind up to 10 million stone tools in every square kilometre of Africa .
