You are speaking about time in the classical universe as opposed to quantum time.
That's almost correct. Yes, I am speaking of macro time as opposed to quantum time. But not necessarily "classical" time. I'm talking about time described by General Relativity. This is why I prefer to call it "macro" time rather than "Classical" time.

Classical time or "
Newtonian time" was wrong. In classical physics classical time was the same everywhere in the universe. That notion turned out to be false. However, temporal behavior of the universe is a construct of the geometry of the universe. And is Einstein's General Relativity description of time which turns out to be true.

But the geometric constructs of this universe are ultimately defined by heat flow and entropy. This is why the universe will ultimately have a heat death and time will eventually run out.

Broadly speaking, the arrow of time points in the direction of entropy but that does not mean entropy determines the structure of time. They are both moving in the same direction but this does not mean entropy defines classical time.
Entropy ultimately determines that fate of macro time, and the structure of the universe. Or you might say that entropy is the recognition that the structure of the universe will ultimately end in a heat death. In other words, entropy isn't a "
thing". Entropy is simply the observation that the structure of the universe will ultimately smooth out and time (
being a product of the structure of the universe) will also then come to an end.

Entropy and disorder are not the same thing
I never said they were. In fact, I actually disagree with that idea. Our notion of "
order" is totally arbitrary.
Let's say we have a glass containing two different colors of water. In the beginning the two colors are completely separated. As time passes the two colors eventually mix together resulting in the glass ending up containing one single color.
Which condition is more "
well-ordered"? As far as I can see it's entirely a matter of personal subjective opinion.
Some people might say that the two separate colors were the more orderly state. While other people might say that when the entire glass contains a single color, that condition is more orderly.
So the whole notion of order and disorder is open to subjective opinion. Actually in the case of a glass of water containing two different colors of water no work can be extracted in either case. So from a thermodynamics perspective this situation cannot produce any useful work anyway.
I actually disagree with the famous Boltzman's definition of entropy. I prefer the original definition of a path integral. I think the path integral conveys the true meaning of entropy.
Because recall, even you said that time caused by the structure of the universe.

That's correct according to General Relativity (not Classical Physics).
And the reason entropy exists at all, is because the geometry of the universe is ultimately deteriorating (
i.e. become less well structured). In fact, you can actually say that this is the
cause of entropy. The universe isn't obeying a law of entropy. Entropy is simply the observation that the geometry of the universe must ultimately deteriorate.
This process is best described by path integrals.

On a side note. Boltzman's definition of entropy appears to also be a correct observation of the behavior of the universe in general. In other words, time not only runs down due to the deterioration of large scale structures, but large numbers of individual things, such as pigment molecules will also tend to mix together over time due to statistical consequences. But this is only true when those objects are free to move around randomly. Obviously if the pigments are cast in concrete then will not mix together over time. At least not until the concrete itself has broken down. But in this latter case it's the "
structure" that is breaking down. And when the structure breaks down that's a one-way event that leads to a universe that ends up with no structure.
And since structure is required for intelligence, intelligence itself must ultimately deteriorate and come to an end. So intelligence eventually ends because intelligence is dependent upon structure and structure dissipates over time.

What about quantum time?
In the quantum world there is entropy. In other words, there is no large scale structure to break down or dissipate. So quantum time can be eternal. In other words, there can be eternal changes of state in the quantum world that can continue dynamically changing forever. There is no macro structure to run down or dissipate.
But at the same time there can be no intelligence in the quantum domain because intelligence requires large scale structure. So while the quantum world can be eternal (endlessly dynamic) it cannot be intelligent.
So my point is that you can either have eternal time (
quantum dynamics) or you can have intelligence (
large scale organization), but you can't have both of these things existing simultaneously.
Therefore there cannot be any such thing as an eternally intelligent God.

Having said this, some forms of Pantheism can be true.
In some forms of Pantheism the idea is that the quantum domain is God (although they didn't know about the quantum domain when they invented Pantheism). They see the quantum domain as God "Sleeping". God is not dreaming, he's not thinking, he's not doing anything other than being in a state of pure existence. They call this state a state of "Pure Bliss". And God does not even have any thoughts when in this state.
Then God "wakes up" (
this would be what we call the Big Bang). And takes the form of a macro universe. Eventually God becomes conscious and intelligent in this state. In other words, God becomes us. This is Pantheism. We are God experiencing the macro world.
In Pantheism this state last for a very long time (the entire length of the existence of the physical universe). At the end of that time God returns to the state of pure bliss where there are no thoughts, no ideas, no intelligence.
And then the whole process repeats endlessly.
They kind of God can exist.
But that's clearly not the God of Christianity.
In fact, the Pantheistic kind of "
God" is actually compatible with secular atheism. The atheists would simply say, "Why call it God?" That's just an unnecessary label for something that naturally keeps reoccurring.
