If you want to go down a rabbit hole, look into biblical and other references to how important and common the acacia tree was, and then consider that it's thought to be a significant source of DMT. (The second fresco in the article has what appears to be an acacia tree in it). One can only speculate what someone could have imagined if they were around one while it was burning and they inhaled it. The analog feedback patterns one sees when their senses are impaired are by almost all accounts, geometric patterns like fractals, and so the discovery of geometry and association of it with mysticism could have a common chemical origin. If there was something to be known or learned from psychedelic experiences, a national security service would need to know and understand its boundaries. Given radio was only recently discovered, people new to the idea of communicating over long distances using invisible energy would have had to consider whether there was some chemical connection. I'm not saying it's aliens...but it may very well be all drugs.
