Skepticism of Evolution
Though skeptics of evolution are not (necessarily) Creationists, they do not fully subscribe to evolutionist dogma. They may be former evolutionists, and often become Creationists.
Several philosophers and practitioners of various faiths are skeptical of evolution. These people are often skeptical of the Old Earth theory as well.
However, they do not or do not yet identify as Creationists or believers of intelligent design. Rather, they are simply skeptical of some of the ideas put forward by evolutionists.
