provable
yes, theologians argue that logic is enough to prove the existence of God: https://en.wikipedia.org/wiki/Kalam_cosmological_argument
If you refute logic/reason cuz you only like science that you experiment on, then you're too caught in the material buddy. Remember that math doesn't seem to follow the scientific method either you know ? Please don't tell me you refute it too.
I notice that the word I know in my language kalam is a little different from theology, but theology is the closest translation I have.
