Nine2five, man, we've talked about this.
I'll just start by saying there's not a standing body authority over CI, no pope or committee saying "This is our creed." Same as there isn't one of, say, Christianity. There are divisions and some divisions get behind leaders. So anyone claiming "I've talked to a CI guy and I took CI down!" is like some faithful-to-progressivism, confident Leftist talking to a random on fedi--or even to some "big follower account" somewhere--and saying they "DESTROYED (YouTube all caps) the ideas of the Far-Right!!1!"
The label "CI" is no more useful than the label "Christian." It's only a label of which beliefs are in common--not a statement that all (or even most) beliefs are in common.
Keep that in mind as you mull over things.

Alright, so.
I'm just hitting bullet points because we've talked about this.

Edomites are from Esau (Edom). Esau himself was down from Adam, and Esau took two Hittites for wives to spite Isaac and his mother. (His mother lamented that if Jacob followed suit, her life would have been pointless.) The Hittites were Canaanites. The Canaanites had mixed with Kenites. The Kenites were from Cain.

(btw The Canaanites had also mixed with the Anakim, the Rephraim, etc., who were the Nephilim. This is explicitly stated.)

Cain was not from Adam, but was of Eve.

The verse describing Cain's conception is volatile, changing more than the verses around it. "I have born a child of a lord / with the help of a lord" and its variations are among these, missing the "And Adam knew his wife" at the beginning.

(Yes, God's Word will never change. No, our recording of God's Word doesn't keep with that. Otherwise, Revelation wouldn't end with a warning about the possibility of adding or subtracting text, we wouldn't have clear examples of verses and entire passages added centuries after the NT authors wrote (even as late as the 16th c.), and we wouldn't have multiple versions on the same bookstore shelf. "The" Bible is not infallible because we who handle it are not. We turn it away from what its authors wrote--by accident at times, or with intent at others.)

The description of Eve's interaction with the "Tree of Knowledge of Good and Evil" is the same as descriptions of sexual temptation in writings just as old. The epic of Gilgamesh is an example.
Or in Proverbs of an adulterous woman.

Note that in the garden were "all the trees which God had made" and *in the midst of those* were the Tree of Life (which is God, who would "be like a Husband" to us) and the Tree of Knowledge. (Hmm? Are we talking about an actual tree still?)
Eve didn't eat from a tree. She conceived with an angel, just as happens 3 chapters later with other women (Gen 6:1), for which God floods the land of the descendants of Adam and starts again with Noah.

Alright, I'm cooking chicken now. Again, those are bulllet points of things I've already written more at length about with you specifically. I didn't even touch Malachi, Isaiah passages (ch 63, for example and its relation to the latter chapters of Revelation), the two Revelation verses I'm sure everyone on fedi knows (2:9, 3:9), and more and more.
