Question

The question is a bit simple and, in my opinion, somewhat silly, but it seems called for in relation to the Rabbi’s philosophy, and I’ll explain.
Not long ago I happened to watch a discussion by the Rabbi on a channel called Head-to-Head about the rationality of belief in God.
The Rabbi’s argument (of course, if I understood him correctly—because if not, then from the outset the question probably isn’t valid)
was that logical laws, such as the main law discussed in the debate—namely the principle of causality (that is, that everything has a cause)—are arguments that are true regardless of the universe or the reality in which we live, and will always be true.
The main argument of the guy the Rabbi was debating was that outside the bounds of the reality we know, the logical laws as we know them in our reality do not necessarily have to apply, and therefore there does not necessarily have to be a cause.
The Rabbi’s answer (again, to the best of my understanding) was that it’s true this is not logically necessary, but according to the required logic, no matter what reality you are in, these laws would apply simply because they are always true.
And that brings me to the question I started with: if in every reality there must be a cause (or even outside reality, because I think it’s possible to call outside reality another reality in its own right), then what is the cause of God, so to speak? That is, He must have a cause, because we operate according to logical laws that are always true.
