View that God’s existence or lack of it is unprovable or unknowable either because he, if he exists, is so above humans, or that science cannot observe unobservable things. Honestly, within the framework of skepticism, this is technically true! Even if unlikely, you cannot disprove it... as He is said to live in another world. I used to be atheist, and still am, but I at least have to say this is technically more logical.
In fact, I think it was because I was confused by my theism type. It is not possible to prove, but it is very strongly the case that there is no God. I think it's because belief and scientific knowledge are two things, and as long as both sides remain unproven, we can have an opinion of any possibility in the spectrum, except scientific certainty, as it requires an observation or a proof/disproof of his presence or his absence; otherwise, within Epistemology we may never know of it.
