Theistic evolution and evolutionary creationism are similar concepts that assert that classical religious teachings about God are compatible with the modern scientific understanding about biological evolution. In short, theistic evolutionists believe that there is a God, that God is the creator of the material universe and (by consequence) all life within, and that biological evolution is simply a natural process within that creation. Evolution, according to this view, is simply a tool that God employed to develop human life.

Theistic evolution is not a theory in the scientific sense, but a particular view about how the science of evolution relates to religious belief and interpretation. Theistic evolution supporters can be seen as one of the groups who reject the conflict thesis regarding the relationship between religion and science – that is, they hold that religious teachings about creation and scientific theories of evolution need not contradict. In describing early proponents of this viewpoint, it is sometimes described as Christian Darwinism. A very similar view is evolutionary creationism.
