Excellent short definition of (real) Creationism.
Of course popular antievolutionary creationism is not pantheistic or naturalistic either. Instead it is deistic. It wants to point to a God who is "needed" to explain certain phenomena in the natural world, on the presumption that natural causes are inadequate because they lack or exclude God. But the corollary to a God who is occasionally present is a God who is occasionally ABSENT; which is deism. Likewise the assumption that natural causes exclude God, or can be sufficient (even of limited sufficiency) without God, is to exile God from portions of reality, which is again deistic as opposed to theistic.
True. There are also many varieties of deistic creationism as well. As much as I don't believe in evolution, I don't think it is literally-true that God created in six 24-hour days several millenia ago.
