In the sense that the supernatural claims and many historical accounts made by biblical authors have no basis in reality, of course you’re right. That doesn’t mean there’s no value in the academic study of the Bible. If you have no interest you can dismiss the whole lot as nonsense, but there’s a lot of insight (and by insight I’m not talking about capital T Truth about the nature of reality) about the development of thought in Europe and the Near East to be gleaned from the Bible.
