Isn’t pantheism the same thing as atheism?

[Alan V]

A God without the ability to make choices is not a God by the usual definitions.  He is powerless rather than powerful.  

There are 2 kinds of systems: deterministic and non-deterministic.

You can be a deterministic system and also make choices.

...

If you want that to be non-deterministic, then you want it to be random.

...

A brain just runs algorithms. A human brain has parallelism and is a neural network and so, there are differences between a human brain and a CPU like your Intel i7 and AMD Ryzen, but these CPUs are general purpose. You should be able to create a program that approximates the human brain, although, it will run slow.

Anyway, like I was saying a brain just runs algorithms.
If you want it to be non-deterministic, you would have to insert some randomness here and there.
If you have too much randomness in the decision making process, that brain is going to behave erratically.

First of all, I see "determined or random" as a false dichotomy.  Humans also "fill in the blanks" to interpret situations without enough information (like you are doing), and choose between frames of reference so they have a better idea which algorithms to apply to which situations. Also, humans create their own programs.

Second, even if all humans were in fact determined, they had to be determined by something else.  A God is in a different, unique category altogether.  To be all-powerful, he must be self-determining.  Otherwise there must be another God behind such a "God," just as there are people behind robots.

So my correction, given what you pointed out, is that a God must be able to make free-will choices. I don't see the whole-natural-world-God-of-pantheism doing that. It isn't the simplest explanation for what we see around us.
