Just understanding the historical facts and what the very religion that produced it holds as fact and fiction, because it's not even intended to be factual vs. A bed time story, will make most people realize either their religion is made by fools and liars, or they need to adapt a very symbolic kind of faith.

I have a friend who was a serious muslim so she started reading the quran and then relized at the age of 8 that the whole thing is bs so she stopped believing. Its funny because there are a bunch of people who tell her how shes disrespecting her ancestors and she should at least read a bit into it. She probably knows more about it than 90% of the people telling her about it.

Can they slip the geniologies? They're just there to prove the guy in the story is really truly the descendant of someone holy and important, so add nothing if you just presume the protagonist is a proper protagonist
