In terms of beliefs about the supernatural and God, agnosticism seems to be the most rational positions to hold compared to atheism and theism. I am the kind of agnostic where I don't know if God exists, and I don't even know how I would attempt to calculate a probability for God's existence, let alone actually give a probability.
I think the atheistic claim that God is unlikely seems to be an impossible claim. There are way too many possibilities and factors that would be required to actually determine God to be unlikely. Furthermore, theism is equally illogical since it claims that either God's existence is likely, or certain.
I would argue that nobody has anywhere close to enough information that would enable them to formally, or even informally, determine the likelihood of God's existence. Even visions or feelings that people have aren't anywhere near conclusive enough. Visions and feelings could be delusions, or an alien experiment, or a fake deity tricking you such as Satan, or some kind of hallucination, or just wishful thinking. These feelings or visions can't be used to know if God is real due to the unreliability and unverifiability of feelings and visions, especially considering feelings and visions tend to confirm a variety of beliefs that are often mutually exclusive. Anyways, it seems to me that if people were trying to be as logical as possible, they should be agnostics as i've defined them (not knowing the probability of God's existence and not knowing if its possible to get such a probability).
