Many Asian-Pacific myths share the theme of the heavens being to close to the earth and needing to be raised. Is this simply a metaphor or does this tell us something significant about that period in time? The theme of the great flood is shared by Noah's Ark and the Epic of Gilgamesh and we have found evidence to support that there was an actual flood. So it seems if there is a shared theme in myth across great regions then there was some fact in the myths.
