The Book of Enoch is mankind’s springboard into the understanding of the origins of the cosmos because it introduced our forfathers to the main participants in the creation of all things and over time the thinking of the wise continued the theme but on the whole scarcely took it futher.
First we have the person who started all things - the Head of Days. El. Today called simply God in English by many. The Ancient Greeks’ name for this author of time itself and lord of the calendar was Chronos and later they got a bit confused and called El by the name Cronos too (because Cronos was similar a word to Chronos). Enoch must have called Him An or El depending whether his original work was in Sumerian or Akkadian but sometimes used a term or title later translated Head of Days and Daniel reflected this in the title Ancient of Days. On the whole the concept of time having a chief who is greatest of all divinities continued through history since Enoch.
Then we have a person who came from this Head of Days and in whose name all things of nature came into being, the Son of Man. Later the Orphic teachings of the Greeks called this being Phanes. From chaos this being created order and the Cosmos took shape. Enoch showed how this Son of Man and the Head of Days were always together before the beginning and ever since have worked on all things together governing creation behind the scenes and bringing all the divinity angels into being and assigning responsibilities.
Then we have the oath. The angels knew a great oath by which all of nature takes shape and functions in an ordered way. Angels were later believed in Roman times to swear an oath of office. There might be a relationship there. One monstrous divinity punished breakers of the oath. Orcus. Enoch revealed that an angel Kasbeel is in charge of the oath that governs all things. Wikipedia explains (https://en.wikipedia.org/wiki/Kasbeel) that there were two oaths in the Book of Enoch passage; one that binds the watchers and the other that binds nature. So the first of these oaths might be the oath of office sworn by every senior angel on pain of punishment.
