I agree with you though I suspect our conception of God varies, as it almost must. Probably, correctly understood, existence is beneath God. I see you aspire to be a scholar so I wonder if Iain McGIlchrist has made it into your bookcase? I've been rereading the last two chapters of his book
The Matter With Things: Our Brains, Our Delusions, and the Unmaking of the World. Last night I read the following which I think goes a long way to understanding the ongoing confusion over God's existence. From pp 1860-61:
"That awe and wonder are the end as well as the beginning of philosophy is one reason why God may be a better name than just ‘the ground of Being’ for this creative mystery. A phrase like ‘the ground of Being’, too, may have its conventional cultural baggage - in this case its presumed dullness. ..
So, providing we remain appropriately skeptical about language, we not only can use a term other than ground of Being, but, it seems to me, we must. Metaphysical argument can take us some of the way, but it deals only with the what, not the how. Even the rather abstract question ‘why should there be anything at all? Is not, after all, just an intellectual puzzle. It is a fundamental question - the fundamental question - for human beings; and we miss the point if we suppose it is a matter for abstract reasoning alone.
In a wonderful passage Schelling writes about how we should prepare ourselves for an understanding of any subject:
I believe that in the necessary process of achieving a fit between our understanding and what there is to be known, our present materialist culture has disregarded Schelling’s advice, and contracted the scope of what exists. We are like someone who, having found a magnifying glass a revelation in dealing with pond life, insist on using it to gaze at the stars - and then solemnly declares that if people in the past had such a wonderful magnifying glass to look through, they’d have known that, on closer inspection, stars don’t actually exist at all."
