We claim there never was a nothing. We claim that first there was God, then there was something.
By axiom the effect cannot be greater than the cause, so the something is less than the God thing. Because it is second and therefore less, the second thing cannot comprehend the first thing, since comprehension is just a form of circumscription. Ontological sequence defines epistemology.
The something is rational and comprehensible in its nature, for us, because we are ontologically higher. Hence, science. ≈You cannot fully comprehend another human, for example. Hence, supra (not anti) reason.
The God thing is also rational and comprehensible to every intelligence larger (of course, there are none.) To those smaller intelligences, He is partly comprehensible and infinitally not comprehensible. Not because He withholds, but because He existed first.
The method of thought is the same in all instances: we wonder so that we might know. We wonder at creation, then know it by science. We wonder at God, then know him by faith (which is NOT blind belief, but is a specific mode of knowledge.)
