Briefly, there was once a global mono-cosmology (dates far back into the mists of time) that was based on astronomy (the movements of the heavens) concerning a particular aspect of the astrophysical relationship between the Sun and Earth and the effect that this particular aspect of this relationship has on the Earth plane and the solar system. Central to this scientific cosmology was the concept of the World Tree, which represents the axis of the globe and center of the world, which are two different but related phenomenon (World Axis, Axis Mundi, Center of The World, World Pillar, etc...). The Serpent was the particular aspect. The effect of this aspect and human being's relationship with this effect is the basis of many of the moral codes found in our premodern ancestor's recordings from around the globe. The dressings of this myth vary from culture to culture, but the main players keep turning up in nearly all of them, and common to most all of them is the development of a personal identification with the world tree that results in clarity, transformation, and release from the "burden of time".
Yes, a few of them reference
including the Hopi and Tibetan Buddhist mythologies, and many of them speak of variations on this theme (visitors from other realms).
