Yo, the whole idea of this question is impossible for man to answer. Our brains are wired to comprehend a beginning and an end, but there is the possibility that existence begins, but doesn't end, and there is just the same possibility that it begins and ends. We can't comprehend it either way. Try to imagine living for eternity, then try to imagine non-being. The thought of both are impossible. So whatever ends up happening to us is ultimately a paradox of existence. Since we have defined things such as existence, we expect there to be opposites and such, but really we have created all of these concepts to justify actually being. It's really incredibly paradoxical.
