People believe in the gods that have evolved with their culture because those gods fit properly into a place in their mind where such things exist. Your thesis is that the place itself is invalid, but the arguments you offer are variations that haven't shown themselves to fit as well.
You lay them out in a proper evolutionary chain as "improvements" on Jove/Jehovah, but your chain starts now and leads into the future. The sort of people who believe in literal gods don't live in the future yet. And when they get there, it won't be your variations that they believe in, because you have no intention of doing the work necessary to shape a closed culture over time to become a suitable receptacle for the ideals you propose.
You aren't going to get an answer you can understand about why people believe in something until you make a depth study of
what they believe and have believed over long periods of time. Let me ask you this: why do you act just like them? I mean you, not the real scientists in the forum. You, specifically, act like this is a team sport or military action and they are the other side, and therefore everything they do or say is categorically wrong without even bothering to study the question and think for yourself.
Furthermore, anyone who disagrees with you must be one of them! There's no middle ground, everything is black and white and you don't have anything to learn. This is
classic fundamentalist behavior. In sociological terms, you are using them as a scapegoat to reinforce your denial, everything you hate in them is readily apparent in you except the specific details.
