Where did the fairy tales of ancient Greece and Rome come from?

The origin of myths is the same, that is, ancient people can't explain natural and social phenomena scientifically and rationally, so they weave stories based on their own understanding and imagination. Greek and Roman myths are also some explanations of natural and social phenomena by early Greeks and Romans, which are related to the geographical location, climatic conditions and national character of ancient Greece and Rome.

Greek myths can be traced back to the early ancient times. Besides the myths of Indo-Europeans, they also absorbed the myths of local aborigines. Plus the legacy of Crete and Mycenae. The legend of Chaos, represented by Gaia, Uranus and Knossos, is a myth in early ancient times, while Zeus, Hera, Apollo and Athena are represented by a new generation of gods. The different times when myths came into being reflected the productive forces and relations of production at that time. Roman mythology is basically a copy of Greek mythology, except for a few local gods such as Jaanus.

Although myth is the creation of ancestors, it also reflects the historical situation at that time to some extent.
