By default a religion is based upon myth. You have prevailing theories such as the Ritual/Myth theory which are used to give meaning to myth and the rituals and religions that follow it. On a theological note, myth much like the word theory is what is used to classify all religious tales. Myth is not to be mistaken for a derogatory word.
I myself loves mythology but I would never mistaken those myths for reality and form a religion from them.
