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.
What you are asking others to believe is that the author of that book was the same as the source of the universe. Isn't that a bit like asking them to believe that the author of misspelled graffiti sprayed onto the base of a bridge is the same as the designers and creators of the bridge?
Interesting comparison, but wrong. When you always view anything solely based upon your 5 senses, and those of others, you are wrong all the time. Further, you limit yourself. As I have pointed out before, in cosmology there exists the string theory, based upon tiny "strings" so small they can never be seen. So, your reject it solely because you are not able to detect the strings with your senses ? How about a multidimensional universe ? Many physicists and cosmologists believe there are many many dimensions of which we are totally oblivious. Some believe that these dimensions, that are populated, exist in the very same space we occupy. One of those ignorant ancients, Paul, spoke of this when he described "powers, principalities, and prince's unseen" You, and your fellow travelers going back centuries scoffed at him. However, now, do you scoff at the scientific evidence that shows he may have been right ? ( of course I know he is right)
Because you are ignorant of the purpose of the Bible, it appears to you as it does. If one looks at a map, and decides to follow every road represented on it, rather than identifying the road that leads to your destination, and understanding how the other roads relate to your chosen one, you will see the map as you see the Bible, wrongly.
