What are the similarities and differences between a fairy tale and a myth?

The myth and the fairy tale are similar in that both works are based on fictional events. Both there and there are fictional heroes who may have supernatural properties. The differences lie in the fact that in a fairy tale there is a story about some heroes and their adventures, while in a myth the plot captures more global events, like the creation of the sky or the origin of rain. The fairy tale shows the people how to act correctly in specific situations, and the myth in more global ones. A fairy tale can be written by an author, and a myth is passed by people from mouth to mouth.
