Well, if God is quantum mechanics, then we don't need the word "God" since we already have the math in place for quantum mechanics.
Combine the equations for QM, gravity, and the dark energy constant and you'll have the 1st of 4 tiers in the universal equation.
2nd tier is electro magnetism.
3rd tier is the graviton.
4th tier unfolds the weak and strong nuclear force.
Those are the roots under the surface of things, everything visible are as leaves.
And as you hint at, I might need to drop the word "God" altogether. After all, if I say "The Man" some will automatically assume I mean the corporate "evil white man" immortalized by Homie the Clown. Others might think of the manliest man at the height of what it means to be a fully developed, self responsible Male. Who's right? Neither.
And so to avoid confusion (I am simply talking about a physical human being), I'll describe the shape of the skin, orifices, external and internal structure, mutually dependent and simultaneously arising systems and structures, etc, etc, etc.
It requires a certain amount of circumambulation.
