Henotheism in the Hebrew Bible.

[Huggy Bear]

The serpent, who wasn't a snake, (otherwise it makes zero sense why it was cursed to crawl on it's belly if in fact it was already crawling on it's belly) it was somewhere between a human and ape, close enough to the human species to where it could reproduce sexually with humans.

You yourself stated earlier that certain groups of people have zero neanderthal DNA...

*emphasis mine*

Which can only mean that this neanderthal DNA isn't a result of evolution (or everyone should have it) but of a human having sexually reproduced with a neanderthal. Abel and Seth were the seed of Adam while Cain was the seed of the serpent, which means that some people would have serpent DNA while others wouldn't.

I proposed that the "neanderthal" DNA IS serpent DNA or they are genetically similar.

Well, that’s just plain dumb and stupid.

And the human knew Eve his woman and she conceived and bore Cain, 

Boru

So we're Just going to post quotes out of context?
Genesis
1. And Adam knew Eve his wife; and she conceived, and bare Cain, and said, I have gotten a man from the Lord.

2 And she again bare his brother Abel.

It is possible for a woman to give birth to two children with different fathers, Eve was already pregnant before Adam 'knew her.

Cain is NOT included in the genealogy of Adam.
