It sounds to me like the arguments about the existence of God are displaced from what the essence of the argument is "really" about.
It seems pretty clear from the equations of quantum mechanics that there is a Deity. However, whether She takes any interest in human beings, let alone the quotidian details of our everyday lives, is another matter.
That is where the argument "really" seems to be: if we posit that there is a Deity, what reasons do we have to believe that She cares about our everyday lives or intercedes in response to a prayer? It may well be that She is like a parent with grown children: "I took care of you and raised you to adulthood and gave you all the skills and abilities you need to take care of yourself on your own. Good luck!"
Isn't that the basis of the argument in favor of free will? If we do have free will, then why would God respond to our prayers?
