The question why does entropy flow the direction it does in this universe.
The answer to this question is fully understood within the concept of entropy itself.
You need to understand that entropy is a macro property of our universe, not a quantum property. It is the large scale composition of objects within our universe that causes entropy to occur. In other words, large scale objects are made up of a very large quantity of smaller objects. And this is the cause of entropy.

For that to happen the original universe had to have entropy flow in both directions. This is why Carroll had entropy flowing in both direction.
Entropy cannot flow in both time directions simultaneously. Also, I'm quite certain that Carroll did not have entropy flowing in both directions. What he may have done is proposes the time can flow in both directions. But in order for that to occur there could not be any entropy occurring at all in either direction.

According to the laws of physics, there is no reason why an egg that falls to the floor and break and splatters all over the floor could not happen in reverse. There are no primal laws of physics that prevent this from happening. However, it never happens, and never will happen in our universe because of the thermodynamic law of entropy

Why?
I just told you, because of the thermodynamic law of entropy. Entropy is why a broken egg will never spontaneously put itself back together again. An egg is a macro object composed of trillions of molecules.

I'm quite sure that Sean Carroll knows that our universe has a very mandatory arrow of time.
His theory is an attempt to describe why entropy flows the way it does.
I'm not sure what you're talking about here specifically. I do believe that Sean Carroll has asked how we can explain the initial low entropy state of our primal universe. Although, for me personally, the answer to this question is easy. Our universe was born from a quantum state which had no entropy at all. Non-directional time.

Entropy is a construct of this universe and effects matter in this universe.
That is correct.
This is not necessarily correct. In fact, if we accept that our universe began as a quantum fluctuation then this is necessarily false.
Time is not a construct of this universe. However, uni-directional time is. In other words, on a macro scale, because of the effects of entropy, things much change according to the law of entropy, thus giving "
Macro Time" a uni-directional arrow.
But "
Quantum Time" does not need to obey entropy (in fact it cannot obey entropy), and thus "
Quantum Time" has no direction. In other words, "
Quantum Time" is simply dynamic motion that has not past or future but rather it only has an eternal dynamic "
Now".

That means that God would not be made of matter and would be unaffected by time. Action on a timeline is a construct of this universe. God is present at every point on the timeline acting at every point on the timeline. All of eternity would be the same moment to God.
Why call that "
God"? It's just the Quantum Domain. Moreover, it cannot have any organized intelligence, sentience, or intent, precisely becasue it lacks entropy. The Quantum World cannot exhibit entropy. Therefore it cannot have sentience, consciousness, memory, or thought.
So why call it "
God"?

We exist and what ever caused this universe had to exist outside of this universe.
Outside? Perhaps "
prior" would be a more accurate description.
If our universe did arise from a quantum fluctuation, then all that existed prior to our universe were quantum fields fluctuating. Our current universe is not a result of those quantum fields vibrating in a manner that produced "macro objects" (i.e. objects made from large conglomerations of quantum vibrations). This then creates entropy which allows for complex objects to evolve and come into being. Including us.

The qualities of God? What's "
God"? As far as I can see all that "
God" amounts to is an ill-defined word that you continually use without any justification at all.

You could call it an universe. And yet again rely on random chance. But in this case random chance will not save the day. String theory predicts that there are 10^500 different combinations or orientations that space can have. Each of these different orientations having different laws of nature. So there must be an infinite number of universes in this multiverse.
First off there very well may be an infinity of universes in the multiverse.
Secondly, String Theory is actually nothing more than an unproven hypothesis at this point in time. It's basically speculation based mainly on ideas of pure abstract mathematics which could be entirely wrong.
String Theory is NOT proven science.

The problem with having an infinite number of universes is the probability of forming a boltzmann brain is more likely than forming an universe like ours.
Boltzmann's Brain hypothesis is also an unproven speculation. This is not proven science. I personally reject Boltzmann's idea and believe that I can show why it is actually a quite absurd proposal to begin with.
In fact, here's a simple example. Take a large box from which all air has been removed. Basically an empty vacuum. Then take small vial of highly compressed air and set it in one corner of the box. Then break the vial. What will happen? The air in the vial will instantly explode out to fill the box. Given enough time these air molecules will eventually even out to fill the box with a "
fairly uniform" pressure.
This is actually because of entropy and the gas is behaving as a macro object.
Question: Given enough time will these molecules eventually return to a highly compressed state back in the corner of the box where the vial was originally placed.
My answer is simply, "No". It won't matter how long you wait, that's never going to happen. Why? Because it's not just entropy at work here, but it's also all the other laws of physics. And there is simply no way for those air molecules to ever return to this highly compressed state.
In other words, "Boltzman's Brain" hypothesis is a joke. You could wait for eternity and you are never going to see a brain accidentally energy from quantum fields in a vacuum simply by pure random chance. It's not going to happen, ever.
So the Boltzmann's Brain idea is a purely philosophical notion that has no place in reality. It's based entirely on pure mathematical probability without taking into consideration all the physical factors that actually exist in a real world.

There's that totally ill-defined word again.
What do you even mean by "
God" if you can't define it or explain what it is?
You may as well be calling it "
The Boogieman". Seriously.
You are arguing that our world was created by a non-material Boogieman.
That's all you are doing. Your argument has no merit at all.
Calling it a "
God" doesn't give it anymore credibility.
