It doesn't start with the premise that God exists. It observes that to avoid an infinite regress of finite events (an actual infinity is an impossibility) the universe must have a cause. This cause must be timeless spaceless and immaterial.

Why are events finite? Why is infinity an impossibility?
A sequence of cause and effects can be broken down conceptually into finite events, right?
Imagine a hotel with an actual infinite number of rooms, if the hotel is booked out, with each room occupied, what happens if another person turns up wanting a room? Now you have infinite rooms and infinity plus one people. When you are dealing with actual Infinity, it gives absurd results
The Hilbert's paradox of the Grand Hotel does not contend that infinity is an impossibility.
If matter cannot be created nor destroyed, then it seems logical to me that it goes somewhere, perhaps rebirths as another big bang.
The time scales at which this may happen are so large that our brains literally cannot comprehend them - far beyond billions of years (at least that is what is stipulated by some that study these things). Of course, we have no way of ever playing that out and witnessing it.
I probably muddied the water using Hilbert's hotel as an analogy in a way other than what the paradox was originally used.
In Hilbert's paradox the statements "there is a guest to every room" and "no more guests can be accommodated" are not equivalent when there are infinitely many rooms.
My point is more like, what happens to the person in the end room?
Our inability to observe or conceive such large time frames doesn't prevent us from conceiving this time frame plus one. Therefore the time frame can't exist as an actual infinity.
That doesn’t make sense. There’s nothing to state that a time frame plus one is proof of no infinity. Plus one just continues the infinity.
The general consensus is that we lack knowledge about what happens to the universe after it cools. It’s all speculation without any proof whatsoever.
I think we are talking about different things.
There is a difference between potential infinity, which refers to a procedure that gets closer and closer to, but never quite reaches, an infinite end, and an actual infinity, or completed infinity. An infinity that one actually reaches; the process is already done.
Dealing with a mathematical concept of a complete infinity, such as complete sets of natural or real numbers is different to the question of whether infinite things exist physically in nature.
