once you read Genesis 6:4 IN CONTEXT, it becomes clear that height isn't even what they are referring to.
That's how you know the Book of Enoch is bullshyt.
Hopefully you learn how to read the rest of the bible "IN CONTEXT" as well.
And I wouldn't call Enoch total nonsense. Jude 1:14 quotes Enoch 60:8 word for word.
