Just because a theory is unfalsifiable does not mean that it's not true. It just means that science and logic are insufficient to refute or confirm the theory. Where science and logic are not capable of shining a light on reality, we can only rely on non-logical and non-scientific beliefs and philosophy.

For example, scientists tend to hold the belief that the laws of the physical universe are constant. But in fact, there is no __logical__ reason to believe that. It is merely an inductive belief that could be violated tomorrow. The theory of constance transcends scientific experimentation and logical proof; it is simply held as an axiom (which could plausibly be wrong).

Beyond logic and science, the multiverse theory is just as plausible as the universe theory. Your intuition tells you that simplicity implies a universe, where others see that simplicity implies a multiverse, where still others find no reason to believe that reality is rooted in simplicity at all.
