In my experience creationists are unable to do this because the 2nd law does not preclude evolution. Why? Consider the following:
A. for a system to become more biologically complex, it often has to INCREASE its entropy not decrease it. Example: which object has more thermodynamic entropy, a dead cell or a living adult human. Answer: adult human by a factor of about 100 trillion. Why? Use principles of calculating standard molar entropy as a chemistry student will use, and one will see a living adult human has more entropy for the simple reason a human has more atoms than a dead cell.
B. which has more entropy, a frozen dead rat near absolute zero or a living human being lying on the beach sun bathing. Answer the living human being because it has more atoms than the rat and because it is at a higher temperature. The rat being near absolute zero has entropy approaching zero.
C. which has more entropy a flying 747 or a small pile of junked aluminum cans?Answer: 747. A 747 has 6.94 x 10^7 J/K entropy compared to a pile of junked aluminum cans that would have on the order of a 10^2 J/K entropy. These calculations should be doable by a college chemistry, physics, or mechanical engineering student.
Given these considerations, why should creationists say that reducing entropy is important? In view of these calculations, it seems that increasing entropy is also valid! Unless creationists can demonstrate reducing entropy is important to creating living organisms (which they can't do), then it is rather irrelevant to discuss open or closed systems, the universal increase of entropy etc.
CONCLUSION:
Creationists should avoid using the 2nd law as an argument against biological evolution. At the very least, if creationists are determined to use those arguments, they could first attempt to affirm or falsify the three examples of entropy I just provided.
PS
the Clausius definition of the 2nd law
the Kelvin Plank definition of the 2nd lawHeat can never pass from a colder to a warmer body without some other change, connected therewith, occurring at the same time.
an alternative form of the 2nd lawIt is impossible, by means of inanimate material agency, to derive mechanical effect from any portion of matter by cooling it below the temperature of the coldest of the surrounding objects.
In any cyclic process the entropy will either increase or remain the same.
