The History of Psilocybin

There are theories that the human capacity for religious belief came because our ancestors took a shitload of psilocybin. The first documented military use of one of these substances was by Hannibal Barca in around 184 BC. There have been studies like the Good Friday study that at least provide pretty good evidence that the kind of religious experiences people have on these drugs aren't any different from other kinds of religious experiences right?
