“…the SERPENT said to Eve, “You will not surely die. For God knows that in the day you eat of it your eyes will be opened, and you will be LIKE God (KJV says “ye shall be as gods”), knowing good and evil.” (Gen. 3:4-5)
Notice, that talking serpent was not some snake with magical powers to speak. That serpent is the main adversary of God and man, “The great dragon was thrown down to the earth, and his angels with him. The dragon is that OLD SERPENT called the devil…” (Rev. 12:9)
