Do you mean myth? if so, here are some prompts you can work off of
The story of how ice was created, you could start off with a goddess who was warm hearted into something that became cold and distant and she was the goddess of seasons and that's why we have winter now
you could come up with the story of how we talked. How people used to not have mouths but the gods decided to give us something to be able to communicate better so we could worship them. Splitting the empty space to make mouths.
You could do a lot of things. Typically myths are either about how something came to be or how a god messed up another god's day by killing the person they loved or just royally flipping them off.
