That is an excellent question!
I also used to wonder about Enoch a lot, particularly because the Bible mentioned how he "walked with God". I mean, to be able to "walk with God", must mean that he was pretty important, right?!
And then, when I'd heard that there was a Book of Enoch, but that the Book of Enoch wasn't included as a part of the Books of the Bible, I became much more interested in him and what was written in the Book of Enoch.
Based on my own experience in attempting to learn more about Enoch and the Book of Enoch, I'd have to agree with MickS, that the Book of Enoch was most likely taken out of the Christian canon because it doesn't really fit with the story that the powers that be want to tell/want to have told.
As far as there being a specific link between Enoch and Jesus, it makes sense that there would be. After all, Enoch's "walking with God" and Jesus' being "received up in Heaven" do sound like very similar experiences.
Now that I think about it, one of my friends did mention this website to me recently, that does talk a bit about Enoch and Jesus.
There was this one article on the website that talks about Jesus' real name and his travels in England, India, China and Tibet during the New Testament’s “Lost Years of Jesus”. The website says that it was during these "Lost Years" that Jesus resurrected the ancient teachings, wisdom and techniques of Enoch - the only man listed in the Old Testament to have “Walked with God”.
