Okay kiddo, so there was a group of people a long, long time ago called the Hittites. They lived in a place called Anatolia, which is now part of modern-day Turkey. Just like you and me, they had their own stories and legends called mythology.
One of the main gods they believed in was Teshub, who was the god of the sky and storms. They thought he controlled the weather, like rain and lightning. They also had a goddess named Hannahanna, who was the goddess of the earth and fertility. She was responsible for helping crops grow and making sure animals had enough to eat.
The Hittites also believed in creatures called "dragons" that were really big and scary. They thought they lived underground and would come up to cause trouble. But they had a hero named Telepinu who could defeat them and make everything right again.
There were also lots of other gods and goddesses in their mythology, like a god of war named Tarhunt and a goddess of love and beauty named Shaushka. They thought these gods and goddesses could help them in their daily lives and protect them from bad things happening.
So basically, Hittite mythology was a way for the Hittites to explain the world around them and give meaning to things that happened. It was important to them and helped them understand their place in the world.
