Where is my mistake?
Well, I think your mistake is not so much one of logic, per se. It's that you're taking on a project that people worked VERY hard on in the time of Aquinas, only to find that it was just unsatisfactory. Remember that in the Middle Ages, following the Crusades, Christian Europe became exposed to the philosophy of ancient Greece (which had been mainly known to the Muslim world at the time). Rationality and logic suddenly became important, and seemingly a way to legitimize theology.
But the problem is that God is
impossible to affirmatively prove even if he
does exist, and logic cannot prove the existence or truth of something in reality.
This is why modern philosophy has basically given up that project. Descartes, despite offering a God proof of his own, did a lot to damage God proofs by putting the rational man at the center of all knowledge. And since then, in various ways, everyone from Spinoza to Kierkegaard has undermined the God proof. Kierkegaard is the one from whom the "leap of faith" idea famously comes, i.e. belief in God is NOT rational.
