As a noun, possibility is defined as a thing that may happen or be the case. So in my questions the universe would be that thing or case. Since the universe is here and it had a beginning, according to the scientists, then there had to be a point in time that the universe was a thing that may happen or be the case. Else this nothingness that is said to have existed or not existed could not pre-date the universe at all.
To be clear, nothing can (including nothingness) pre-date the universe if that is when time began.
