“Supernatural” is a word we use to describe things we do not understand from a “natural” perspective, but who is to say whether at some point we gain an understanding that renders the former the latter? As a wholistic outlook on reality, the prospect of an eternal Creator bringing all things into existence and governing them is not all that fanciful or mysterious, but actually a rather natural way to understand the universe, much like science does, yet with great limitations which begin with flawed observers.
That’s a possibility. That is, that the natural and the supernatural is simply a division between what we currently know and don’t know. However, there is another possibility that there are things beyond the natural universe that are not from here, but temporary visitors so to speak. Who can say.
