Yes, indeed.... I have read Enoch (in fact a couple of versions, too) and it’s very interesting. Now, from what I see strictly from the Bible, itself, that’s quite enough to explain the very *basic* idea of what happened. And that’s sufficient, actually.
To read Enoch does give something additional, but — I would have to be careful about attributing any degree of authority to it, other than the Scriptures, themselves. It’s interesting reading, nonetheless. I just won’t use it as authoritative, that’s all. (I believe that the inclusions of certain books of the Bible are also part of the “divine inspiration” of Scripture, to the extent that I won’t take any other outside source.)
But, those other places in the Bible do indicate further “episodes” of the same, at a later time.
Oh, I absolutely agree when it comes to authority. Scripture is it and the only thing I trust unequivocally. That said, there’s a lot of interesting “what if this is true” reading available in sources like Enoch. I personally rank its credibility at perhaps 75%. The Bible is a solid 100.0%. :-)
