I'm not suggesting it would die out completely. There are always some adults who will believe anything. Look at scientology
But if you waited until people were adults, had learned about the world, and had learned how to weigh evidence and basic scientific reasoning. And then told them:
"There is this super-being who created the planets and the universe and all life in a week, and he is still around and controls everything but you can't see him. and he lives in a magical place called heaven which nobody can see or visit, but when you die even though your brain rots you still keep thinking and you go to this magical paradise where you stay for billions of years and never get old. And this magic super-being had a son that was a normal human by getting a human women pregnant. and this son lived for a short time 2000 years ago and did lots of amazing tricks in the town he lived, like healing leprosy with his mind and turning bread into fish. and he was executed but came back to life three days later, and showed no signs of putrification you would expect. And he was actually the magic super-being himself, so he was really his own son. and a lot of other stuff really happened too. Like a man lived inside a living whale, and another man put all the animals in the world in a wooden boat, and somebody lived 800 years, and someone was magically turned into salt"
Do you think many modern adults who had never heard this explanation of the world before would believe it? Or would Christianity lose 95% of it's followers within a few generations?
milksheik: So you never heard about god until you were 28? nobody mentioned it to you? How does your religion feel about lying?
