Would you trust a Middle Eastern goat herder from 2000 years ago to even fix your toilet? Probably not I would think (they'd probably be so amazed by your toilet that they'd start a new religion to worship it or try to have you killed for being a magical wizard with toilet magic). Then why would you trust them to understand the nature of the universe and existence?
Even if there is some kind of cosmic entity that created some part of the universe which then branched out into other things who's to say any of the human religions have any freaking clue as to what that is, the idea that is has to be some kind of space daddy/Santa Claus that actively gives two sh*ts about what you're doing on a daily basis is very much likely a human conceit.
