It is certainly not a scientific law, as is the Second Law of Thermodynamics, which it contradicts. Creationists, therefore, insist that the evolutionary philosophy must simply be wrong. Evolutionists point to two possible ways out of this difficulty. One is to deny the universality of the entropy principle. Since man is quite limited in knowledge, and since he is able to make observations on only a very small part of the vast universe, he cannot be certain that the Second Law applies everywhere in time and space.
Empirical measurements can never establish universal certainty.
This stricture is philosophically valid, of course. However, wherever and whenever the entropy principle has been subjected to scientific test, it has always worked, with no exception. Though we cannot be absolutely sure that the total entropy of the whole universe is increasing, we can say that, wherever it can be scientifically tested, the entropy in any given portion of the universe is increasing. Thus, a baby grows into an adult, two animals may multiply into a population of thousands, man's store of acquired knowledge accumulates to tremendous proportions. Even in the inorganic realm, simple elements may combine naturally to form complex compounds, and molecules may grow into crystals of beautiful complexity.
