Even creationists believe that almost all the processes of life (metabolism, respiration, digestion, reproduction, locomotion, etc) can be explained using biochemistry and physics. They differ from materialists in that they believe people have a soul and they do not believe that materialism can explain the mind, intelligence or morality.
What I am wondering is do creationists believe that non-human animals can be explained in materialistic terms. Do chimpanzees have a soul? They exhibit complex behavior, emotions. They are social animals. Can materialism account for chimp behavior? If so, are humans that much more complex that they require a soul to explain their behavior?
