I don't have anything to add to this conversation as I'm in agreement that the "supernatural" is simply how humans have historically described natural phenomena that is not yet understood.
Now... what I do find interesting is the shared art. I've seen similar styles, but not this piece. I looked it up and thought I would share because I find it to be pretty rad.

The Flammarion engraving is a wood engraving by an unknown artist. Its first documented appearance is in the book L'atmosphère : météorologie populaire ("The Atmosphere: Popular Meteorology"), published in 1888 by the French astronomer and writer Camille Flammarion.
The illustration depicts a man, dressed as a pilgrim in a long robe and carrying a walking stick, who has reached a point where the flat Earth meets the firmament. The pilgrim kneels down and passes his head, shoulders, right arm, and the top of the walking stick through an opening in the firmament, which is depicted as covered on the inside by the stars, Sun, and Moon. Behind the sky, the pilgrim finds a marvelous realm of circling clouds, fires and suns. One of the elements of the cosmic machinery resembles traditional pictorial representations of the "wheel in the middle of a wheel" described in the visions of the Hebrew prophet Ezekiel.
