Question

Hello Rabbi. One of the assumptions of the cosmological argument is that the existence of the universe is not necessary—that is, that the universe is a possible existent, belonging to the category of contingent entities in our experience (and therefore the second assumption applies to it: that anything whose existence is merely possible requires a cause). One of the explanations you gave for this in the booklet on the cosmological proof was the scientific theory of the Big Bang, which says that the universe was created at a certain point in time. But according to the theory (correct me if I’m wrong), the universe expanded from a state of a single singular point that may have always existed. If so, what makes the universe not a necessary existent?
Thank you.
