Primitive humans is high and is seeing the gods of the forest and the nature, start to make up stories about those trips under subjective changes in perception, thought, emotion and consciousness caused psychedelics, dissociatives, and deliriants.
That is the base of all cults/religions, whatever.
Dead Sea Scrolls are cool, but no differ from the trips written by our ancestors.
John M. Allegro was an adviser on the dead sea scrolls to the jordanian government.
In his book "The Sacred Mushroom and the Cross: A Study of the Nature and Origins of Christianity within the Fertility Cults of the Ancient Near East", he points the primitive trips from the dead sea scrolls. He points that christ is a cover up story for the use of Amanita muscaria.
