Why the book of enoch? The angels from that book were imprisoned and is not exactly canonical. A better reference would simply be 'angels' since they come from heaven which means sky. Unless you have a legit reason for using that old text which might be a fake.

Hard to consider them angels in a traditional sense since their presence always seems ominous.

I don’t really mind if certain scriptures of books were cut out of the official Bible. In, fact, it piques my interest more. 

Maybe book of Enoch specifically is a bad example , but I just align with these creatures being some type of fallen angel or demon and not space creatures .
