I think the Genesis story is far deeper than that. Why TWO trees?
So let’s step out of the box. Suppose, for the sake of argument, that G-d created more than one pair of “man”. And they were each given the same two trees. One was knowlege and one was immortality WITHOUT knowledge. Those who would have chosen immortality would not have known how to survive a world like earth...let alone have “dominion” over it. Mindless servants that would need everlasting shepherding, no freedom of thought, no capability to adapt, no need to be fruitful and multiply because they were already immortal, and incapable of independent thought or free will.
Somehow, I don’t think that was ever what G-d intended.
So they were “conceived” in Eden, which might well be a metaphor for womb, innocent as babies, but babies must be nurtured in the womb and are completely and utterly dependent for literally everything on the body they inhabit. They can’t stay there forever. And once they leave the womb, there is no going back. That “garden” is closed to them forever. Hence, the angel at the gate.
It is my opinion, of course, the Genesis 'story' is the least understood book of the whole Bible. Moses was not here in the flesh from the 'beginning' and did not literally experienced what he penned of Genesis. And interestingly Moses was educated by the Egyptian monarchy so he was NOT a dumb slouch sheep/goat herder.
I consider Genesis not only a 'history', but a 'key' to the road-map the rest of the holy prophets and apostles were used to guide any individuals flesh journey.
The two trees are symbolic and an allegory not literal trees. Trees as are used throughout by the prophets, from Gideon cutting down the 'grove', to that parable of the trees of Jotham recorded in the book of judges, and etc., even Christ cursing the 'fig' tree points back to Genesis and Jeremiah.
But this notion that Eve represents the cause and reason for poor man's fall is basis 101 instruction by the majority of Christian teaching. I even had a woman making a trip over to visit me with an instruction she had been given at a Sunday church sermon about how Rebekah too was evidenced of the 'natural' deceptive ways of woman. Now it was a STUPID man preacher that spoke without knowledge or understanding that wanted to put woman in her place.
The Genesis account says that all three individually 'sinned' were judged and held accountable for their own individual sins. Now I really do not see how tall any man stands by using Adam's whimpering out blaming the LORD for that woman the LORD gave him as anything to be beating their chests as cause. Most especially, when it was before 'that woman' was even formed that the man was given the one on one instruction to stay away from that specific and particular tree.
Rather seems to me all these many 'days' later that no one outside of the loving arms of the LORD is or will be immune to the lies and deceit of the magical tree of the knowledge of good and evil....
