Should religion be 18+?

I think it would be a good idea for religion to be 18+. Sure, when you're a kid hearing stories about a politically incorrect Willie Nelson lookalike skipping on water and turning water into booze is good as a bedtime story, but imagine reading that as an adult? If you had never heard of the Bible or any other religious man-made book until you were 18, and then purchased a copy and read it, would you say to yourself this is the most logical sh*t I've ever read in my entire life, and I need to get billions of other people in on this?! As an adult, you would appreciate the general gesture of religion trying to induce morals, but you would also realize it was a fictional book that no self-respecting supernatural power would agree on publishing. If booze has age limits, then religion should too, for they both destroy unneeded brain cells.
