Evolution does not attempt to explain the origin of life. It is simply a history of the process of life. With the secret cause of life evolution has nothing to do. A man, therefore, may be a materialistic evolutionist or a theistic evolutionist; that is, he may believe that the cause is some single unintelligent impersonal force, or he may believe that the cause is a wise and beneficent God.
