Of course, the intelligent man appeared much earlier. The first ancient representatives of intelligent man appeared as a result of evolution about 200-350 thousand years ago in Africa, from there the species spread around the world, replacing the existing populations of Homo erectus (human erectus) and Neanderthals. 40 thousand years ago, the area of habitation of intelligent man spread almost all over the Earth. Agriculture appeared in the Mesopotamian region more than 10 thousand years ago. Thus between the spread of Homo sapiens as the main species of apes around the world and the discovery of agriculture was about 30 thousand years, and beginning with the appearance of the first representatives of Homo sapiens before the advent of agriculture has been more than 190-340 thousands of years.
