Since when does the human pretense of "objectivity" determine what does and doesn't exist?
Since the Enlightenment we've become more and more self-conscious about subjectivity. That's why reasoned enquiry, including scientific method, endeavors to maximize objectivity. And the justification for reasoned enquiry, including scientific method, is that it works in reality better than any other alternative.
The reason it doesn't work for religion, as far as I can tell, is that supernatural belief is not concerned with reality. Hence it has no objective standard of truth.
Essentially you've arbitrarily defined God out of the possibility of existing by defining it irrationally
All I've done is carefully distinguish the objectively real from the purely conceptual / purely imaginary.
And not only have we never found God in the world external to the self, but the whole concept of God is composed of imaginary, not real, qualities ─ omnipotent, omniscient, omnipresent, perfect, eternal, infinite, nothing of biology, morphology, color, metabolism, life cycle &c. So there isn't even the concept of a real God, a God with objective existence.
Nor is there any coherent concept of real "godness", the quality that a real God would have and a real superscientist who could create universes, raise the dead &c, would lack.
and then decided that God doesn't exist.
All you need to do to demonstrate that I'm wrong is to show me a real God. But no one does.
