A long time ago people looked up at the sky and saw a giant bulls head taking up a 3rd of the sky. This is how Baal worship started. This thing became God when it flipped the poles and set half the world on fire. Devil horns.

In reality it was the passing of the red kachina. It has a debris field around it so in the sky it looks like it has wings or horns.

The "Devil" is a celestial body.
