Creationist critics often charge that evolution cannot be tested and therefore cannot be viewed as a properly scientific subject at all. This claim is rhetorical nonsense.~ Dr. Stephen Jay Gould (born:1941-09-10 died:2002-05-20 at age:60)
On the contrary, it is the creationists with an untestable hypothesis. Creationism makes no predictions. There is no telling what a god will do.
