We don't have words known to have come from any god. What we have are words attributed to a god, which are really evidence of nothing except that several somebodies are claiming that a god told them something long ago. We don't even have evidence that they believed what they wrote themselves. When you open the book and read it, you find evidence within that the god described within could not have existed. It's logically impossible by virtue of it having been ascribed mutually exclusive attributes like the famed married bachelor. Do you think that such a thing can exist? Of course not, not if we mean married and bachelor in the usual sense (not a bachelor married to his work, for example), and we mean in the same person at the same time. We also find evidence in the book that its authors knew no more about the world than their neighbors, further evidence that those are not the words of an entity with superhuman knowledge or even one with contemporary human knowledge.
