Permit me to point out that mythology and religion are NOT the same thing.
Mythology tells stories which make a point, but are not meant to be taken literally. Religion also tells stories, but they are "historical", and are meant to be taken literally. The Greeks were perfectly aware of this distinction, and had a clear separation between mythology and religion, even though the same characters appeared in both.
