I think of it like this:
It's fairly straight forward to build the other numbers from a starting value, 1, but defining 1 itself requires a full understanding of the infinite structure, and the other things it can build. So you can view 1 as both more basic than the other numbers and also more complex than any of them.
Similarly, the argument would be that God is both things: nothing but the fundamental notion that the universe does stuff (or is), and also the full complexity of structure built from that fundamental doing.
In the same way that mathematics ultimately tried to eat its own tail -- using advanced theory and structures to loop back and define its base structure -- science is attempting to tell the story of how a singular type of fundamental perturbation self-acting can give rise to the plethora of structures and phenomena we see, and must inevitably do so.
That we keep running in to the same sorts of definitional loops, fractal structures, notions of duality, etc across both efforts suggests something of the nature of God -- or at least the computational structure of the universe we live in, as it is built atop a singularity.
Getting a little further afield -- modern physics suggests that reality can be interpreted as a quantum computer operating on universal scale and timelimes, so in a very real sense, we're just a subset of the singularity computing. I would argue that many primitive people intuited this fact before we had the terminology to really articulate it, and that we see this splashed across religion, covered by later political additions.
