Claim CF001:
The second law of thermodynamics says that everything tends toward disorder, making evolutionary development impossible.

Response:
1. The second law of thermodynamics says no such thing. It says that heat will not spontaneously flow from a colder body to a warmer one or, equivalently, that total entropy (a measure of useful energy) in a closed system will not decrease. This does not prevent increasing order because
* the earth is not a closed system; sunlight (with low entropy) shines on it and heat (with higher entropy) radiates off. This flow of energy, and the change in entropy that accompanies it, can and will power local decreases in entropy on earth.
* entropy is not the same as disorder. Sometimes the two correspond, but sometimes order increases as entropy increases. (Aranda-Espinoza et al. 1999; Kestenbaum 1998) Entropy can even be used to produce order, such as in the sorting of molecules by size (Han and Craighead 2000).
* even in a closed system, pockets of lower entropy can form if they are offset by increased entropy elsewhere in the system.
In short, order from disorder happens on earth all the time.
2. The only processes necessary for evolution to occur are reproduction, heritable variation, and selection. All of these are seen to happen all the time, so, obviously, no physical laws are preventing them. In fact, connections between evolution and entropy have been studied in depth, and never to the detriment of evolution (Demetrius 2000).
Several scientists have proposed that evolution and the origin of life is driven by entropy (McShea 1998). Some see the information content of organisms subject to diversification according to the second law (Brooks and Wiley 1988), so organisms diversify to fill empty niches much as a gas expands to fill an empty container. Others propose that highly ordered complex systems emerge and evolve to dissipate energy (and increase overall entropy) more efficiently (Schneider and Kay 1994).
3. Creationists themselves admit that increasing order is possible. They introduce fictional exceptions to the law to account for it.
4. Creationists themselves make claims that directly contradict their claims about the second law of thermodynamics, such as hydrological sorting of fossils during the Flood.
Edit: Here are a couple other bits
* Formation of the universe from nothing need not violate conservation of energy. The gravitational potential energy of a gravitational field is a negative energy. When all the gravitational potential energy is added to all the other energy in the universe, it might sum to zero (Guth 1997, 9-12,271-276; Tryon 1973).
* Creationists cannot explain origins at all. Saying "God did it" is not an explanation, because it is not tied to any objective evidence. It does not rule out any possibility or even any impossibility. It does not address questions of "how" and "why," and it raises questions such as "which God?" and "how did God originate?"
