Just 50,000 years ago, people had neither art, nor religion, nor a strong ability for abstract thinking. However, as a result of a sudden round of evolution, which, according to scientists, became the greatest milestone in the history of mankind, people suddenly acquired all the basic qualities and abilities that have characterized them until now. In his new book, the famous researcher of the extraordinary, Graham Hancock, studies this mysterious phenomenon in detail , which actually divided the entire history of mankind into two parts. In the course of his “intellectual investigation,” he tried to establish the true nature of those forces that shaped the image of modern man. In search of answers, Hancock studied many religious rituals and cults based on the use of plant hallucinogens, and was able to prove that they are all based on similar images and visions. The facts collected and systematized by the author are arranged in a clear, scientifically verified logical chain, indicating that such hallucinations may be nothing more than the perception of other worlds and dimensions hidden from us.
