The Biblical God and human free will

I have been attempting this weekend to read from Genesis Two only what I find in Genesis Two.

Here I propose a solution, to defend Israel's and - now - Christians' maintenance of this text: God let the Serpent in, on purpose. Call it a missing verse in Genesis Two.

The Serpent - as Interloper - is not under God's control. The Serpent either came from the outer Chaos directly, or else was one of those protogods whom YHWH defeated. We haven't gotten into "Lucifer" doesn't matter; this hypothesis works equally for Nyarlathotep or Cronos.

I also don't claim supreme power for God. I do claim He knows what transpires in this universe, let alone in that (much less complex) walled garden which was Eden. So if the Serpent got into God's own greenhouse, He let it in.

In fact, God let it in at the start. When He explained to Adam and Eve how the Garden worked - "if you figure out this hack, which is RIGHT THERE IN THAT TREE OVER THERE, this Garden is going to collapse" - that command only makes sense after he had imbued Adam and Eve with the ability to make that choice.

The ability to make that choice, independently of God's will, is exactly Chaos. It is the Serpent.

After it was all done, Adam and Eve would name their third child Set. The Egyptians named their god who defeated the chaos-snake Apophis, also, Set. Possible coincidence. Possible not.

UPDATE 7/29: I've discussed Lucifer. He's still irrelevant.
