Is The Forbidden Book of Enoch the Key to Unlocking Ancient Mysteries?

I found this very interesting video on YouTube about the Book of Enoch. Although our Protestant canonical Bible quotes from it and a few passages refer to some of the material in it, it was left out of Western Christianity. The oldest version of the book is a part of the Ethiopian Bible and tradition predating the Roman Catholic and Protestant canons and traditions by centuries. Should it be included and treated as authorative like the 66 books that we believe are scripture? I will tackle that issue in another post but check out the video.
