It is easy enough to write a book, claiming divine miracles and conversations with the deity, when one knows that shortly after he is dead that no one will be able to claim for certain that he was deluded as opposed to divinely inspired. No one hears or experiences any miracles today because none of it happened back then either. Once one realizes that it was all fictionally created, it becomes easy to understand that man tends to prefer fooling himself into the comfort of belief than accept there is no magical sky daddy looking over us all.
