If science by definition, cannot posit the existence of a supernatural force, then science cannot be used to prove the absence of a supernatural force. For instance, if I determine a priori that no matter what I observe, I shall never observe X, I cannot then turn around and argue, "Ah ha! In all of my research I have never observed X, so I have now proven that X does not exist."Creationdesign
That's it. Case closed. Since creationisn and religion make no claims, science cannot refute those claims that were never made.
"We're gonna make darn sure that no one on our side of salvation ever claims anything." Remarked Dean Thoroughby of the anti-discovery institute. "If we just sit down and shut up, they're gonna have to do the same."
"They walk around so High and mighty saying that god didn't make the earth. Were they there? Huh?"
