Two types of scientists:
Suppose some astronomers are looking at Jupiter through a telescope. Call this Group A. While they do this, another group of material engineering researches confiscate the telescope and analyze it's material properties. They look at it's shape and the shapes and situations of it's components. They examine each piece for it's physical properties and interactions and for it's chemical properties. Finally, they publish a complete physical chemical description of the telescope and insist that this is all there is to it. Call this second group of scientists, Group B. It is quite likely that Group A will say wryly to Group B, "No that's not all there is to the telescope. One thing that is a fact about the telescope that is not in your description is that you can see Jupiter through it".
Group A might be amused by the selective approach of Group B, saying that they looked at only what they wanted to and prejudiced themselves against the most important feature of the telescope. And then after a laugh, Group A returns to their study of Jupiter.
But Group A turns out to be trying to determine a physical and chemical description of the Jovian planet. They also want to determine it's physical, mechanical, and chemical (including possible biochemical) features, with the belief that when they have this they will have a true and complete description of Jupiter.
And here Group B may justly fault Group A for it's own selectivity. There is the same difference between what we see when we look at Jupiter and the alleged final description of Jupiter. Just like Group B, Group A has neglected the most important fact about Jupiter, namely that Jupiter is itself a certain kind of "scope", showing us an object distinct from the true description of it's extended and extrinsic interaction. Whatever may be found in this description, Jupiter is also and on top of that an intentional object and an embodied artificial substance.
We cannot really separate the idea of the supernatural from the natural into air tight zone. How "ordinary nature" presents itself to our minds is more that the instrumental conditions that are correlated with that presentation. So even the ordinary objects of the world are signs of supernatural realities.
