It's a lot to unpack Linda, but for a moment think of the layers upon layers of interpretation that is required to arrive at a conclusion like the Universal Sovereignty (aka Great Controversy) doctrine of Adventists like the JWs.
Think of religion as a process of reinterpretation rather than revelation.
Words and symbols of one generation take on new relevance when seen in new novel ways by a later one. The Eden story in Genesis is part of the (J ) Yahwist story of creation. He is a clever writer who uses imagery and symbols from his surrounding culture in fresh ways. The goddess worshipped throughout Middle East as the "Mother of all" was symbolized by a serpent and tree. Here the worshiper of Yahweh takes those symbols and recasts them as the agents of death. The man is tempted by the woman Eve (defined as 'the mother of all') by means of a snake and tree. The woman gets pain and domination, the tree is never heard from again and the snake gets humiliated by having to crawl on the ground without legs and bite heels of people who kill snakes whenever they get the chance. This process of reinterpretation does not end there. The symbols that once played a small role in a small story, fascinated readers, centuries later, who understood these words as a code for spiritual secrets. Suddenly the snake was not just a snake but reinterpreted as code for a spirit being, the fruit became sex or something of cosmic importance.
I see that the rest of your comment shows an awakening of your mind. Keep asking questions.
