Who is Prometheus and what does he do to anger Zeus?

Prometheus is a figure from Greek mythology known for his intelligence and as a champion of humanity. He angered Zeus, the king of the gods, by stealing fire from Olympus and giving it to mankind, which enabled progress and civilization. This act of defiance not only challenged Zeus's authority but also undermined his control over humanity, leading to severe punishment for Prometheus, who was bound to a rock where an eagle would eat his liver daily.
