Incidentally Sword, I’m a bit surprised that you returned to the “alternative worldview” error given that you were corrected on it so comprehensively a while back.
Just to remind you, the issue here is essentially the difference between subjective and objective truths. You can have any worldview you like including, as Nearly says, a belief in Zeus if you want to. What these worldviews provide though is only subjective truths: Zeus, God, Colin the Leprechaun etc are true for the people who believe in them, but not – so far at least – for anyone else.
If you do want to build a bridge from the subjective to the objective though, you need common and consistent inter-subjective experience. I can do that with natural phenomena – if you and I jump out of the window, we’ll have an identical experience – so we call these truths objective. You on the other hand have no equivalent test for “God” (or indeed for Zeus).
And that’s your problem. Ironically, it’s the self-referential claim “God” that’s circular, and so epistemically worthless. You’d need to find some way of breaking out of that if you wanted anyone else to treat your claim as something other than just guessing.
