I agree with everything you said here. Except I'd challenge your 95% figure. I think it's 99+%. The larger question when it comes to the idea of 'God' is this; if a 'God' does exist, does it exist independent of human beings creating it? That to me is an intriguing question. I know I won't get an answer, but it's food for thought. The problem with theorizing an Intelligent Creator is the lack of evidence, and the completely superfluous idea that Universe had to be created by some entity, since no religion ever explains where that entity came from. God isn't necessary for existence. There is an ultimate question that can't be answered, and that's how it all started. Whether it's where God came from or where what we observe came from, that is still a question that can't be answered. At least not yet.
Good points and I am basically on the same page with everything you wrote.
I definitely think God, the Dao, Brahman, Nirvana are probably human constructs. They may not exist independently of our language and cultural norms.
But, to me at least, they may represent anthropomorphic avatars for something our intuition senses: that there may be a higher truth which remains incomprehensible to us.
