* However, if "evolution" means the proposition that all life descended from a single, primordial protocell by variation and natural selection alone, or other similar claims then creationists dispute the falsifiability of the proposition, asking, "What test can be conducted to show this did not occur?" The problem is similar to the problem of "I drank three glasses of water six weeks ago." If there are no witnesses, Creationists argue, then there is no way to test the claim and that the assertion is therefore not falsifiable. | * However, if "evolution" means the proposition that all life descended from a single, primordial protocell by variation and natural selection alone, or other similar claims then creationists dispute the falsifiability of the proposition, asking, "What test can be conducted to show this did not occur?"
