Can something come out of nothing? Does ordered existence emerge from a completely disordered nonexistence of rules? Is nonexistence a non-concept? Is "nothingess" just a vacuum, as we like to think of it, and nothing ever comes of it?
We don't know, we're monkeys! We're dealing with concepts that are so completely inapplicable to the layer of existence we take for granted that any notion that we are equipped with the tools to approach such a problem at all is completely absurd! Get out while you still can!!!
But really, it is rather absurd that people think they can even begin to approach these kinds of questions with logic, when we do not actually know to what existent or how logic should apply to anything that might exist outside our universe. I just wouldn't bother; it's a question that's completely and totally impossible for any human to approach, no matter how intelligent they are.
