One of my pet peeves with some creationists is that they quote definitions like this as though they have some authority. Then the supposed authority of that definition becomes part of the basis of their attack on evolution. The alternative is to look at the definition, expose its flaws, and work toward a better definition. It is not within the competence of science alone to determine whether a natural process is supernaturally supervised. Since these people are teaching our children, we need to set them straight.
People are personal.
God is personal. That is not the same as saying evolution is unsupervised. There's a world of difference. The NABT statement on teaching evolution.
