As a "words person" I'd say that "Science" is a field and "scientific concepts" exist whether anyone manages to explain them to anyone else or not. I'm not even sure what, exactly, the question means by "higher power". To me, though, using words well IS a "science", rather than either an "art" OR, as many people see language and words, as "nothing" (or at least as "nothing that's worth much of anything).
The 'higher power" are all the scientific concepts that exist regardless of who, if anyone, understands them or wishes to understanding of them and who or what they are to someone else.
Maybe I'm biased because, as I said, I consider myself very much more a "words person" than a "science person" (in general and if one is choosing one over the other), but scientific concepts are also at play, and at the root of, the ability to use language well; so they aren't two completely unrelated and separate things (as far too many people tend to think they are).
In many ways, "fields of study" or "areas of skill" only matter much within the context of human beings/human society and advancing overall understanding. Scientific concepts exist regardless of who understands them. Communication and one kind of "language" or another has always gone on within one species or another in one form or another. (That goes back to the thing about scientific concepts being in play, and at the root of, the use communication/language.)
I'm not particularly comfortable with the choice of wording of this question (specifically, the choice of the words, "higher power"). Some people will say language (or at least the potential to use it effectively)
comes from a higher power of one kind of another - those scientific concepts/"forces" of the universe, or maybe an ever higher power "out there" or "everywhere". All I know (think) is that in a present-day world that understands scientific concepts better than they've ever been under stood before by human beings; and in a world that is both more or a mess and less of a mess than it's ever been, the effective and skilled used of language (as well as respect for its value) would seem more important than ever.
