It is telling that this person (PvI) starts with dismissing outright a very real possibility: The universe is like this because it happened this way. In an infinite set of time, which is possible since we cannot prove this universe does NOT exist in an infinite state outside of itself, it is possible that this universe came into being and coagulated in a way as to make it like we see in this moment of infinity. Just because you are _finite_, does that imply everything that is not you must also be finite? Just because our universe appears finite, does that mean everything that could exist not within our view of this universe must also be finite? There is rational explanation that considers the universe to be cyclical wherein it expands and then collapses and starts over. Repeat that infinitely, you could have an instance where our universe is created. It is reasonable.

You can't compute the likelihood of the universe existing. You have no clue as to how possible it actually is.
