The theistic proposition is a matter of belief or faith, not supported by evidence, not testable.

I disagree here. I came up with a theory/philosophy or a way for 'theistic proposition' which seems to be pretty good. Not only that, but I tried to counter this proposition from every angle, but it still it holds true for me. It is not supported by belief/faith, but I derived it from science/maths/philosophy. Basically, I created my own version of God.
