LSD was invented in 1938, I have to disagree. Moses had to be tripping when a burning bush spoke to him, lol!
You are assuming that the story is true and not somthing that was added later to add credibility to Moses.
All praise to Albert Hofmann.
Now there's an idea for a religion, Albert as Godhead? Hunter S Thompson as the first saint. DMT and Psilocybin used in the Sacraments. The Women's Institute serving 'mushy tea' and if you really want a burning bush we could always grow a little weed. Think of the added benefits like Who's going to want to go to war while they're tripping?
Yahweh was a tripping ancient volcano god. A volcano god's lava typically sets bushes on fire, don't ya know.
Pharmacological LSD was first manufactured in 1938 to mimic the hallucinogenic effect of naturally occurring substances, such as magic mushrooms and Ergot, used in ritual magic and religion for millennia.
It is like saying no one used apple tree bark as a pain killer before the patenting of aspirin in 1899. They are both acetylsalicylic acid, only one is in a concentrated form.
