Test any true statement and it tests true. You find supporting evidence and more importantly, you find no contradictions. Obviously, when you find contradictions, the statement does not test true. Sometimes, the statement needs reformulating – often it is an overgeneralization such as a rule stated to have no exceptions. Sometimes the statement cannot be changed because it was declared to be the word of god. Well, pretty obviously, when a statement is contradicted by the evidence, it was not the word of an infallible or omniscient god. A reasonable assumption is that it was the word of a fallible human being pretending to write down the words of god.
