The difference is that people are not "talking serpents." Whenever I hear/see that type of language, I immediately cease to take the post seriously!
I can understand why you dismiss it out of hand since what may believers claim is that God caused a snake to speak by some miracle in magical place where people could live forever and God walked with man..
I think thats a load of crap too.
I am saying something different, less spectacular, even obvious, that scriptural references to talking serpents or talking donkeys, sheep, dogs, pigs, goats, wolves, parasites, vultures, bottom feeders,etc., even angels and demons, are references to human beings just like people still compare other people to animals in the wild to either insult or praise another person.
In the garden of eden all of the wild beasts of the field that the Lord God made that Adam named were figurative comparisons to other tribes and well known types of people. Some did not think very deeply like swine that do not ruminate. some were scavengers like vultures that feed on the dead, , some religious charlatans, talking serpents who take advantage of the gullible, some are pack animals like wild dogs, others like teeming vermin, some were herd animals, some dumb as an ox, strong as a bull, others like an eagle, some like a lion, and then there were trees, like thinking men, with deep roots who produce fruit that is pleasing to the eye and good to eat..
Knowing this is the key to understanding the wisdom hidden in the divine commands, the key that opens the gate that leads to the tree of life, the key to understanding the mystery of God.
