I would like to add that the explanatory scope of this kind of theism would be none. This kind of theism just seems to push the problems one step further, into an unfalsifiable plane, so this way it somehow is better.
Atheism usually presents that the universe is all there is. If this is so, the question of a cause of the universe losses its meaning as the universe would be necessary itself.
Theism presents a further, unfalsifiable and unknowable reality that is the cause of the universe. Now, to avoid an infinite regress, this unknowable and unfalsifiable reality is defined as necessary.
Now,

Theism is not rational, because no rational argument can be made to show the existence of such an unknowable reality. If so, present a non-fallacious one on
this thread.

Theism can incorporate any truth that is available to non-theism, while at the same time offering a plausible, internally coherent explanation of ultimate origins that is unavailable to non-theism.
The explanatory scope of theism adds nothing to the one of non-theism about ultimate origins, as beyond the universe all is speculation. If you find saying that the universe doesn't have a cause (that it's necessary) illogical, then you can hardly defend it for the necessary reality you are presenting, which cannot even be shown to exist in principle, much less its necessity.
Why God doesn't need a cause but the universe does?
Why is it rational to look for the cause of the universe outside the universe?
What is meant by outside the universe?
When theism gives us a reason to think there could be things outside the universe, it will gain credibility. Until then, it's just unsupported claims.
