I just think the Bible has gone through countless rewrites and translations, like what's on the dead sea scrolls vs KJV or others. As language evolves, the meanings do too, and there is lots of lost context. Lots of stuff is pretty clear, but the first books early post-creation, not so much..dispite how much the Jews revere and protect the Torah so much has been lost and changed. Like a very long game of Chinese whispers or telephone.. maybe oral tradition would have actually been better to preserve meaning with language changes, but writings have their own benefits.. overall it's significant, and holy, but it has its gaping-wide gaps from my view. This nephilim stuff is something I pay zero mind to.
