Again, by definition, a person who believe in G-d does believe in some form of creationism. OTOH, I know many hardcore creationists who believe evolution is a tool of G-d. Result? Believing that G-d and evolution are necessarily mutually exclusive is not all that open-minded. From what I've seen and heard, the mainline evolutionists go into all sorts of contortions to try to remove all vestiges of G-d from evolution. Not, what I would consider, an open-minded position.
Fallacious argument. You could also argue that since the Theory of Gravitation does not have any vestiges of God, believing in the Theory of Gravitation is not, an open-minded position.
Evolution tries to explain the progress from point X to point Y. Whether or not there is a God is irrelevant and thus not part of the theory. Evolutionary theory is totally consistent with the existance or non-existance of a God.
