It is remarkable that Gobekli Tepi turns out to be a temple and that all those cave drawings are also representations of Shamanic visions. This is good though.
The only "true" religion is the religion of first hand experience. All religious systems are built on the mystical experiences of one individual or a handful of individuals sharing a religious experience. Gobekli Tepe is the oldest temple in the world and it gives us a window in the world of prehistoric thinking. Ancient people valued experiences of altered states of consciousness as meaningful sources of information supplied by God[s]. This is the first form of religiousity. It is truly the first religion or the oldest religion.
