At the end of an exciting quest that takes him from the ornate caves of southwestern Europe to the rock shelters of South Africa, and the Rise of psychoactive substances, such as ibogaine in Africa or ayahuasca of the Amazon jungle, the author attempts to understand ornement and why, less than 50,000 years ago, humanity suddenly invented art and religion. The hypothesis is then gradually emerging that our DNA harbours a “code” allowing access to another world, another dimension.. Could it be that behind evolution is an intelligence that we are only beginning to understand? This work unifies, in a new and singular theory, the testimonies of abductions by extraterrestrials or by fairies, the mystical experiences, the encounters of shamans with spirits, as well as the magnificent drawings and figurations, half-animal, half-human, of our ancestors of the Upper Paleolithic. This surprising link, both universal and supernatural, leads the reader to the frontiers of the fantastic.
