It wasn't considered 'canon' in the West due to false doctrines: fallen angels can't talk to 'God', the Garden of Eden still existed after the Flood, 'restoration' during 'tribulation', a bunch of angels that appear nowhere else, Enoch coming back to earth after being taken to 'Heaven', etc.
This wouldnt have been any less believable than Jesus' resurrection if it was considered canonical and accepted into doctrine. And there are canonical works in the West that imply Enoch was taken into Heaven alive by God Himself to be put into a prominent position...yet what came of it? I just feel like it was discarded largely due to the story of Enoch's life being far less believable (365 years) than Jesus (33 years). There are parts of Enoch's tale that could have been adapted in, and were originally written in Aramaic both before and after Christ, yet for some reason, it isn't necessarily historically accurate. I just dont see the complete consistency except a bias to maintain dogma.
