G. K. Chesterton wrote that if a highly crafted key was found in a desert somewhere, and afterwards it was found to fit a particular lock, that would be reason to suppose that the key in question was made to fit that lock.
If a set of ten laws, written down 3000 years ago for a bunch of nomads, is to this day accepted as being universally valid within and without Christianity, it might well be supposed that they are more than just a random set of ideas. Rather, it might well be deduced that the Ten Commandments are brilliant statement of the minimum conditions upon which any civilized human society can function.
Science can demonstrate that the physical universe is made in one particular way, and not in another. The Ten Commandments propose that Man is made to live in society in one particular way, and not in another; that personal beings are responsible to a personal author of the universe.
