Aside from the obvious sources of external energy one must also quantify the affect of natural selection as in input and feedback path into the equation. Creationists present an incomplete equation and then attempt to use it as proof to refute science. God certainly created life and guided its ascent, but the process He used wasn't crossing His arms and nodding His head like Genie or wiggling His nose like Samantha Stevens.
Point 1: It seems to me that if you have a closed system, entropy will increse. You don’t have to quantify anything.
Point 2: In using the second law of themodynamics, they are not trying to refute science. They are refuting atheism.
Point 3: Your comment about Sammantha Stevens is irrelevant.

If the system is not closed, does that mean it is unbounded?
