So, we must derive the existence of the Creator before we can go off supposing that He arranged the universe to be what it is via its beginning. This is not negative, but just saying that His identification must come first; otherwise, all thereafter would be just idle talk.
We’re not real interested in the fine details of the mechanics of the implementation, for it is the message of reality that matters, not the method, which is kind of like that music still comes across as music whether from a live band or a music player, but we could entertain major shifts such as that all is accomplished through consciousness; however, in that case, the intricate brain would not really be doing much of anything, it not really being there but for show as a grand hoax, as dream stuff, so, let’s at least stick to reality as we know it, it showing consciousness as requiring a brain, that it can go away to anesthesia, etc.
Why would a Creator have to be so?
