If the ‘kicking out’ of Adam and Eve was due to ‘growing up’, there’s be no original SIN, and thus, no need for Jesus.
I’d have to say that the view you put forth in post 16 is incorrect.
Attempts to “allegorize” Genesis invariably lead to a denial of the need for Jesus’ atoning sacrifice. I think those behind perpetuating these attempts knows full well that that is the result and goal.
