OK ... there's been sufficient unanimity in responses, I will update my understanding of the question 'is the concept of God a privileged hypothesis?' to mean a God that is again personal and mindful. A God that is like a human being (but superior) is clearly a privileged hypothesis, reflecting the limitations of human psychology and imagination, and I have no reason to challenge that.

There really appears to be nothing to argue about regarding atheism/theism. I'll keep on the lookout though.
