So, to connect this back to the OP, you seem to be saying that belief is NOT 'nothing when compared to experience.'
In other words, as I tried to parse your veiled concepts, belief is more important than experience.
I perceive so far that you have reasoned that there must be a universal deity, and therefore you believe in it, BUT you have not provided any comments to suggest that you have experienced said deity, nor how you would recognize said deity if you were to encounter it, or recognize a lesser but very mighty deity should you encounter that.
By contrast, while I can follow that reasoning, to me it is ONLY reasoning, because I have never experienced (to my knowledge--because how would I know?) an almighty deity, or even one several orders of magnitude less almighty. The largest spirits/powers I've encountered are operating a few orders of magnitude above humans...maybe on the scale of the solar system...but as far as I can tell, nowhere near a universal almighty.
And I really doubt any human's ability to recognize the difference between something that is 95 percent almighty and 100 percent almighty, to use your terms.
