Legend is based on fact and then stretched, and myth was never real to begin with.
Explanation:
1. Legend was based on some fact, until the truth was stretched so far it became just a story. A myth was never a fact to begin with.
This is significant because a legend has evidence, which may be incorrect, but a myth does not have any evidence whatsoever.
2. Legends are set in a historical period of time from a particular culture that is more recent. A myth is set in the ancient past (hence, once upon a time).
