@neologist,
If you are going to argue this point, the please explain the text to me.
Why is the serpent called a "wild beast that the Lord Jehovah had made"?
Why is the serpent compared to the other animals (i.e. the "most cautious")?
Why were the animals we know as snakes cursed by God?
Your point of view is clearly at odds with the Word of God. If you are going to call it is "misconception" than you should at least explain your reasoning. Revelations doesn't help, clearly the serpent in revelations (which was thrown down from heaven) is different than the serpent in Genesis (which was on of the wild beasts created by God).
