I am amazed at how little this guy knows about the subject he wants to attack others about.To clarify....
"Creationism" in general is a belief that a god or gods played some sort of role in the history of the universe. There are several forms of creationism. For example, within Christianity there is young-earth creationism, old-earth creationism, day-age creationism, progressive creationism, ID creationism, and theistic evolution. Other religions also have their versions of creationism, such as Hindu creationism (which IIRC has something to do with creative cycles).
