This is all I could find on years...Prometheus was originally intended as a direct prequel to the 1979 science fiction horror film Alien, set approximately 30 years before the events depicted in the film. Alien supposedly takes place around 2122. Prometheus had a date of 2093 according to the intro.
According to one legend Prometheus created mankind out of clay and water. When Zeus mistreated man, Prometheus stole fire from the gods, gave it to man, and taught him many useful arts and sciences. In another legend he saved the human race from extinction by warning his son, Deucalion, of a great flood.
