The watchers were special angels whose job was to supervise humanity and help it grow. Some of the watchers came down to earth and started having sex with our women and teaching us things we werent ready for. They are considered gods but they are created subordinates to the true god. The old pagan myths are actually real stories of what happened. Paganism is all the same religion, tailored to the ethnicity of its followers worldwide. Because these stories have analogues in places with no contact with europe, the middle east or india this indicates that humanity did in fact originate from a single point and spread around the world, also much more recently than we are told. This central point is called babylon. After the flood, the old religion was revived. When the humans didnt spread out as they were told, they were separated by race and language at the tower of babel and took the religion with them, telling it differently in their own languages.
