Myths have them. Numerous gods and demi-gods. Some religion also hint at their existence. Muslims for example believe djinns are more powerful than humans which technically makes them demi-gods since they can do things which humans can't. Christians and Jews have this story about angels [gods] some of whom expelled from heaven and a second group angels who came down to earth so they could get married and they produced hybrids who were the heroes of old. Since these fallen angels never did depart and their offspring had nowhere to go [when they died] since they were children of angels, does it mean that we still have these gods and demi-gods around?
