Since Abraham and Moses probably never existed in RL, I'ma give 'em a pass on having TLE. Joseph Smith was a con man, he knew exactly what he was selling. Interesting but speculative. It seems clear that MOST people who currently report religious experiences do not have TLE unless it's way more common than I thought, but an alternate brain state similar to what meditation produces does seem to be involved when they try to study it in a lab.
I'm not anti-Christian. I'm anti-stupid.
