Child rape and repression are prevalent in most religions, they must be true! This human nature argument that you are making is just evidence that each of these religions are not special. Many religions mention a virgin birth and ressurection. This doesn't make me more inclined to believe the jesus story. It's evidence of how uninspired they were in writing it. 

...dragons, vampires and zombies are mentioned in cultures across the world. This doesn't serve as an "illustration" to "prove" the existence of them or the possibility at least that the authors of those stories had divine help. 

Its interesting how hard people reach to draw evidence of dieties. It gets harder and harder as we understand more of the world around us.
