God took Enoch to heaven just as He did Elijah. It would seem (from a layman's point of view) that if God disagreed with what he wrote, He wouldn't have done that. I have been tempted to read it, or watch a video on YouTube, but haven't done so because it isn't in the Canon.

I don't know why they didn't put it in there. I agree with you.
