Virtual History
A real head-bender is the idea of Gerald Aardsma that the history in the geological record is like the back-story in a novel, but God really only made the world c.5,700 BC. So God didn't make the world with a fake history, but merely traces of a history (or histories) consistent with its present day state...
*sigh* Just how that differs from just faking navels I don't know.
