I and practically everyone (believer or non believer) has always known the serpent in the garden of Eden to be known and referred to as Satan.
Correction:
You and practically everyone you have ever known have always
been taught that the serpent ... was Satan.
I'm not saying it was or that it wasn't. I'm only saying that the story
as written tells of a talking snake, magical trees and ends with a cherubim with a flaming sword keeping people out of the garden. What later people did with this story in assimilating it into their culture(s) and religious beliefs is a different matter altogether.
I offer to you (and Lion IRC) the opportunity to consider an entire sect of Jewish people who did not share your interpretation: the Sadducees.
Acts 23:8
For the Sadducees say that there is no resurrection, neither angel, nor spirit: but the Pharisees confess both.
Lion IRC has made the unwarranted claim that
atheists have some obsession with the Torah, which I find laughable. Talk about not knowing ones adversary. But I digress. The Sadducees were known for their rejection of everything except the Torah when it came to religious matters.
Understanding this helps one understand the clever tale of Jesus encountering the Sadducees. They presented a story of a woman who sequentially married each of 7 brothers. One by one each brother left her widowed. Then they asked "Whose wife would she be in the resurrection?"
Jesus's answer (not that I believe that this story happened as written either by the way) studiously avoids appealing to anything but the Torah. Jesus refers to Yahweh answering Moses and claiming "I am the god of Abraham, Isaac and Jacob." He then comments "God is not the god of the dead, but of the living."
His argument hinges on the tense of the verb I
am. Since he doesn't say I
was the god of Abraham, Isaac and Jacob (people who would have been long dead by the time of Moses) it meant that Abraham, Isaac and Jacob were still alive
somewhere..
This is a poor argument for several reasons, but it is the argument that was used by whoever fabricated that anecdote and placed those words into Jesus's mouth. And it was written precisely because of what many of us here on the skeptical side of this discussion have been arguing all along: The Torah does not teach that the snake was under the influence of a fallen angel nor does it teach of an immortal soul or resurrection. These are interpretations that are read into it by people who already believe in such things, not clear teachings that can be read out of it.
I also feel compelled to point out that the statement I responded to above involves the fallacy of appeal to popularity - a very compelling argument, but ultimately one that is based on the premise that truth is subject to majority vote.
