Explain your concern with eclipses.
Really? I need to explain this to you?
Well, look at the every
daynight moon. It looks relatively bright in the night, like a luminary. But then, when it blocks the sunlight during an eclipse, it looks black. Not luminary at all, rather blocking light and emitting nothing.
About the luminaries, we have what we have though modern science contradicts it. Should we ignore the differences we're encountering and only go with the narrative?
I don't care much about modern science. Why mention them at all? Long before modern science, people were able to recognize that the moon reflects the light of the sun.
How do you think the luminaries work?
I don't know how the sun works. But it's obvious that the moon reflects light (primarily) from the sun, as explained before.
Enoch is referenced in scripture several times which offers the book a notch of credibility above modern pagan science and at least consideration.
You seem to suggest that the "Book of Enoch" (aren't there several such?) was written by Enoch. I don't think so.
