Not compelling to you because you (apparently) cannot leave the bounds of logical thought. But to someone whose experience of Life is unitive, who doesn't feel a sense of separation from life, "God" is a way of being, not a belief system.
I can't really disagree with you. I don't doubt that God is a way of life for believers. But I do think that people who live with God in mind or according to a particular doctrine also have a belief system. They seem to me at least, to be two-sides of the same coin. In terms of compelling reasons to believe that God exists, the atheist or even agnostic, doesn't find any. I don't think this means that “we” are unable to leave the bounds of logic. I've experienced a few things where logic cannot provide any satisfying answers, where I've thought “could there be a spiritual explanation,” but with the knowledge I have and the explanations available, I tend to leave such issues as God and spirituality in the “I don't know box” where it would seem presumptuous to draw any conclusions.
