That is disingenuous framing. One does not need to “believe” that the Bible is false, only lack a belief that the Bible is anything other than another book written by humans.
Besides, there are hundreds of religions with their own holy books. Why should I take yours any more seriously than the Bibliotheca or Dianetics?
To answer, I think there are an utterly astounding number of books in this world and no intellectually satisfying reason to isolate exactly one specific book as having special authorship.
I think it's comparable to Harry Potter. Actually, Harry, Ron, Hermione, Hagrid and Dumbledore set way better example than any person in the bible, while not requiring anyone to believe the world of Hogwarts to be true.
And I do. What are the chances of multiple male authors creating a book that confirms their worldview and lays down the law for everybody else to follow putting them at a very hard to dispute real life advantage vs it being handed down by an omnipotent being?
Let's just say I would be highly surprised if anything related to the spiritual world and related to miracles or the origins of the universe as related in the bible came out to be true in a way that does not agree with hard science.
