But the phrase "something exists" is tautologically true, while the phrase "nothing exists" is a logical contradiction (since the phrase itself and the speaker and the listener must exist). So it's logically impossible for the whole universe not to exist, as long as we can have this conversation or even thought. It's like discussing why 1+1=2 and not 0.
