Well at least the author got the correct answer but unfortunately via an entirely confusing and unnecessarily complex (and incomprehensible) method. It is much simpler and more direct to see that it is an invalid question.
It is invalid because "nothing" is a relative term regarding something that was or could have been present but now is gone. E.g., there is nothing in my pocket. Nothing is not a thing it is a relationship. As with all concepts, "nothing" presupposes that something exists so it is invalid to apply it to all of existence which is how it is used in this question.
As Parmenides beautifully instructed, all one can hold of nothingness is ... nothing (it can neither be apprehended nor indicated).
In response to Leibniz's ontological query "Why is there something rather than nothing?" Morgenbesser answered "If there were nothing you'd still be complaining!"
