Science Looks for True Explanations, Not Just "Natural" Ones
I get so tired of creationists constantly claiming that science only looks for "naturalistic" explanations and therefore a priori excludes supernatural ones. That's a load of crap. Science looks for explanations that are backed up by evidence, and supernatural explanations are only ruled out because there is never any evidence for them.
When creationists say that science is just "methodological naturalism," tell them they're full of shit. Science is about finding actual explanations instead of fantasy explanations. The reason fantasy explanations are rejected is not because science rules out the supernatural, it is because the purpose of science is to weed out things that are untrue, and fantasy explanations are untrue. Untrue explanations never have evidence to back them up, and that's why science rejects them.
When creationists say that science rejects supernatural explanations because it assumes "naturalistic" causes, tell them they're still full of shit. Science makes the assumption that evidence will lead to correct answers. It's not the fault of science that evidence never leads to supernatural explanations: it's the fault of the facts, which are that supernatural explanations aren't true. That's all.
