Until recently, the archaeological community has spread the view that the beginnings of human civilization started after the last Ice Age, which ended around 9,600 BC. All human ancestors prior to this time were recognized as primitive, uncivilized hunter-gatherers who were incapable of communal organization and architectural design. It was only after the Ice Age, when huge 2-mile deep ice caps that covered much of Europe and North America melted, that our human ancestors started to develop and perfect agriculture, forming more-complex economic and social structures around 4000 BC. Archaeologists believed that first cities started around 3500 BC in Mesopotamia and, shortly after, in Egypt. On the European continent, the oldest megalithic sites are dated around 3,000 BC, and the popular Stonehenge is dated between 2,400 BC and 1,800 BC.
This is the established chronology being taught in schools and believed by modern society. Prehistoric societies such as Atlantis have been declared myth.
Until now. New research now reveals that civilized humans were settled on Earth during the prehistoric era.
