I don't think the bible was written by naive people though. I mean all except Genesis which has a reason for it.
@MarioRedfield: Maybe maybe not. But it is still very possible. It's true for every religion. A few millenia ago, people thought the Sun was God and prayed to it. Others thought eclipses were monsters eating the Sun and prayed to God to make it go away and believed it actually worked. The Greeks and Romans flat out made up a ton of stories about Gods that we know for a fact not to be true. And the monsters from the stories were mainly based on dinosaur bones that they used to find and didn't know what they were. And just a few centuries ago, people thought that illness and natural disasters were caused by demons.
There's nothing to say that some of the same things didn't happen in the Bible. I'm not saying that the whole thing is fake. I'm just saying that people have a bad habit of misinterpreting things. So I don't put much stock into what people used to write. I just put my faith in God and take the lessons that were intended from the stories.
