Surely the amount of rice on our plate at 7 o'clock sharp or the mixing of chemicals to produce salt have naturalistic explanations.
Yes. And?
I think this "natural / supernatural" dichotomy is primarily an artifact of a flawed, Western, "Enlightened" worldview rather than anything built into the fabric of the universe. In fact I think that with enough consideration and research (of a philosophical bent) this will probably be shown to have some connection to the inherent "myth = lie" connection some people here also display. Perhaps there is some sort of correlation (I'd use the word "isomorphism" - math geek thing) between the way the Western world sees "science" and the way it sees "truth"; between the way it sees "miracle" and the way it sees "myth". Perhaps by tying "truth" down to "science", and then making "science" separate from the numinous and the mythical / religious, we find that "myth" is automatically tied to "lie". Ironically this is precisely the sort of thing which fuels both fanatical atheistic evolutionism ("since the Bible isn't provable scientifically, it isn't true") and scientific creationism ("since the Bible is true, it is provable scientifically"). Flip sides of the same dualistic coin.

Back to the question. Yes, these phenomena have "naturalistic" explanations. But what is meant by a "naturalistic" explanation? The whole reason why we have that dichotomy up there and why this even arises is because we have let the Enlightenment define our terms unfairly.
Science and "naturalistic" explanations exist because the world has objectively observable orders. Objects falling downwards have constant accelerations, disregarding air friction; heat always goes from hot to cold and temperature always varies according to heat, mass and specific heat capacity; blood flows from the heart out. All these are basically quantifiable relationships between variables. For the first one, for example, it boils down to an equation connecting the time from an object's drop and its displacement at that time (s = .5gt^2) which basically says "at time 1, you have displacement x1; at time 2, you have displacement x2; at time 3, you have displacement x3; ... "
Science is basically just that. Connections between variables. A "naturalistic explanation" is a way of explaining a connection by means of a model about reality. eg, Gravity is an attractive "force", because when objects travel in a curved space-time, the "shortest" path (path of least action, if I'm not mistaken) is a path which brings one mass to another mass due to the curved space-time. Note that this "physical/naturalistic explanation" is really yet another relationship: a relationship between the curvature of spacetime and acceleration, that connects the phenomenon to the theory; and a relationship between the curvature of spacetime and the presence / absence of mass, which allows the theory itself to be proven or disproven. (Which is, by the way, what a "theory" really is in scientific context. You can't say "evolution is 'just' a theory" just the same way you don't say "relativity is 'just' a theory".)
So, a "naturalistic explanation" is really just a dependable relationship between two observed quantities. From this alone: just because there is a dependable relationship between two observed quantities
doesn't tell us why that relationship is there. In some cases, we get yet another relationship between quantities (like in above), and in some cases we have a "fundamental fact" of nature (like the fact that the speed of light in vacuum is invariable). We're like children who observe that the quantity of vegetables at dinner is constant. Really, the reason why it isn't "science" is because we grow up and realise that we can't make a deeper inference about the nature of reality from it. But I believe that to a five-year-old it is just as "science" as "apples fall down" because there is a relationship between two observables.
Given this dependable relationship in nature created by God (which is where theology finally appears), we can draw two possible conclusions:
1. Nature is consistent, in and of itself.
2. God is consistent and causes nature to be consistent.
Why is it that a naturalistic explanation is always interpreted in terms of no. 1? Because we have allowed our minds to be colonised by Enlightenment ideas. The Enlightenment was the age of reason, the time when the human mind was considered the ultimate way to understand the universe. For the Enlightenment, God posed a problem. God is subjective; God raises paradoxes everywhere (predestination or free will? OSAS? grace or works? Three or One?); and crucially the experience of God is subjective and personal. The fundamental way to experience God is through personal encounter with Jesus; and personal encounters are not replicable, even for the same person.
So of course, the Enlightenment thinkers had a problem with God. And then they discovered / synthesised (to some extent) that there was an unwritten order to the universe. Everywhere you went things behaved consistently. Magnets always pointed (somewhat) north; current was always proportional to e.m.f.; etc. And so the Enlightenment thinkers seized on this and took this order to be something intrinsic in nature. A little as if a 5-year-old child had decided that his parents do not exist; and therefore the fact that there is always food on the table at 7 means that every 24 hours the table spontaneously generates food, as if the food is consistent because of the table and not because of his parents. The fact that you didn't need to believe in God to observe all these things (although a belief in the afterlife must have helped pull some dangerous experiments through!) made a concrete argument for a difference between God and science. God, they said, was something in your head since it couldn't be observed outside it; science on the other hand was real since everybody could check and verify it just the way it should be if it was "real".
And somewhere in the midst of it all people decided to forget that just because physical relationships existed didn't mean God wasn't behind them. This deliberate humanistic amnesia was what caused the fake line between "naturalistic" and "supernaturalistic" to emerge. And if I'm right, it also caused the fake line between "truth" and "myth" to emerge, which then led to creationism trying to put the Bible on the "truth" side in naturalistic ways. Which, if it is true, is highly ironic: that this whole approach to defending truth
is based on an atheist lie.
