It is extremely hard to concoct a myth, parable, or fairy tale. Try it. You will inevitably leave behind forensic evidence. So this is one of the means by which we identify those who write history from oral tradition, those who write myth and legend and those who write it as fictions whole cloth. It is terribly easy to detect historical fabrication by forensic investigation of the narrative composition and the history of each fragment.
