Myths
There are many types of myths, and from nearly every place in the world! Each country, continent, and culture has different myths, with different gods, humans, and other creatures. Usually, a myth exists for one of three reasons: to teach a lesson, to explain the unexplainable, or to provide entertainment.

When she plucked a flower from a tree branch, it turned out that the "tree" was actually a nymph in disguise - and in its anger, it turned the mother into a tree herself. This proves that Greeks treasure nature, and detest anyone who kills or disfigures plant life. The myth teaches us not to hurt nature, but to appreciate it how it is instead.

In conclusion, myths are told for three different reasons:...
