If you listen to the Yazidis he was sent to Hell for defying God by not bowing down to us humans, his greatest work, despite God telling Satan to never bow to anyone because he was made of God's essence rather than us, made in his likeness.

So he went to Hell for 10 000 years until his tears put out the fires of Hell, then God forgave him. He also rewarded him for honoring his original pact with God and was given Dominion over Earth.

He took this Dominion and gave us Humans "Knowledge" like the Serpent in the Garden of Eden, only the Knowledge was of Farming.

Thing is, the Yazidis live awefully close to what is thought to be the birthplace of Farming.

When asked to describe Satan, they described him as a Peacock holding a sheaf of Wheat in it's beak, the same image found in Gobekli Tepe, which is thought to be a shrine that taught Farming to the world.

Hail Satan.

Edit: this is just my understanding after reading an article or 2 on the subject, I'm probably wrong about loads of it, but it's all just stories anyway so who cares?
