Epimetheus had created the animals and had gave them useful abilities.
Hello I'm going to teach you to read and write and tell you about our environment.
While Epimetheus was creating and giving the animals abilities Prometheus had went to go and create the humans so they can have happy lives.
After Prometheus had created the humans he had went back to Mount Olympus where his home was and his cousin Zeus had his children Hephaestus and Athena were armed and they watched Zeus risk the wrath of his thunderbolts and taught Prometheus their knowledge of arts and crafts so he can impart the knowledge to mankind.
Hephaestus Punish Prometheus torturously
Prometheus had returned to Earth to teach the humans on how to read, write, and understand on how their environment is.
Later when Prometheus was teaching the humans about the environment he had gave the humans a gift of fire until he had talked about is to how to deceive the gods so they can keep the good fruits to themselves.
When Zeus had later found out that Prometheus had told them on how to deceive the gods Zeus had decided to take away the gift of fire from humankind and punishes them and Prometheus because he had saw the fire and he had decided to command Hephaestus to imprison Prometheus in torturous conditions.
