"Creationism is not science, and shouldn't be in a public school science class — it's that simple," he says. "Often though, creationists do not, or are unwilling, to recognize this." Science, he argues, is observable, naturalistic, testable, falsifiable, and expandable — everything that creationism is not.
falsifiable??
So creationism cannot be falsified because it is entirely false? I do not get this point. :-(
Whether a proposition is "falsifiable" doesn't have anything to do with whether it is true or false. It essentially means "testable". As in, can one think of an experiment that, given a specific result, would show this proposition to be false? If the answer is no, then the proposition is not "falsifiable", and therefore does not fall under what we consider to be in the domain of science.
