Myths are usually defined as traditional stories that are told to convey religious experience, to establish behavioral models, and to teach. Does it really matter if a definitive line cannot be traced from ancient texts? I say no, it does not matter one wit. It does not even matter if they are newly created stories. As long as they still convey powerful messages and fill our minds with awe and reverence, they have done their part and will continue to be valid representations of religion. Do not bow to the pundits who will criticize you for myths that do not follow the traditional story-lines. They are fools. Times change, and to be relevant the stories must sometimes also change to retain a connection with culture. So, with that being said, create your own myths, stick to the traditional ones, or change the old stories to fit your own needs… just continue to learn from them and keep the sacred messages close to your heart.
