But you're talking about the continuity of order and disorder within nature (the domain that's already been scientifically objectified), whereas I'm posing the philosophical question of whether natural order as such can ever be naturalized, so that science would have the last word on metaphysics.

At the Big Bang, the later parts of nature wouldn't have formed yet. So the "point" in which everything was squeezed was no ordinary point. For instance, that point couldn't have been small rather than large since space wouldn't have existed yet. Hence, our understanding of the Big Bang isn't purely scientific. It's speculative, meaning it's partly philosophical, or it's highly mathematical so it's game-like.
