Really? And what evidence do you have for that statement? Please be as specific and detailed as possible.
The Theory and/or Law of Gravity would be one example where supernatural power could be explanatory. Science has yet to explain its origin or cause. Science feels compelled to attribute it solely to natural causes, but even then it seems unable to determine its cause.
As long as science constrains itself to natural causes it will be constrained by its own biases. As it stands, all science can do is observe and quantify gravity here and there while remaining mystified as to how it carries on so consistently from age to age in our world.
That is because gravity is not natural. It is a supernatural force in play under the guiding hand of a supernatural being. Science applies the tag "natural" to the supernatural on a regular basis. Just as it plays around with the word "species" without the capacity to define it (but rather relishes the wiggle room), science plays around with the word "natural" without the ability to define it (unless it necessarily entails the absence of supernatural involvement).
Science will forever be constrained to serving the Creator and His creation. It will always lack in explanatory power. Too bad so many who pretend to be scientists throw unnecessary constraints on the pursuit of knowledge, but that is the nature of the temporary world in which we live.
