I think one of the greatest ironies of the bible is that ultimately, Satan's words to Eve have actually been vindicated as truth. At the very least, a good argument can be made for such a position. Check it out:
"You positively will not die." - Genesis 3:4
Adam and Eve did not die in the day of their eating from the tree. They lived for centuries! Not only that, but they went on to have offspring some of whom would eventually have the privilege of living forever in heaven. Note: Man would not have had the priviledge of having eternal heavenly life had Adam not eaten from the forbidden fruit! Adam and Eve vicariously live forever through their offspring! So in that sense Satan was right in saying they positively will not die. Also Satan's use of the plural YOU when speaking to Eve could be seen as him saying that mankind positively will not die, as opposed to just Eve or Eve and Adam. I know some would say that's stretching it, but Christians also stretch it when explaining how Adam and Eve did not literally die in the day of their eating the fruit as God had said they would.
"For God knows that in the very day of YOUR eating from it YOUR eyes are bound to be opened and YOU are bound to be like God, KNOWING good and bad.” - Genesis 3:5
This was indeed true as can be seen from what is said in Genesis 3:7,22:
"Then the eyes of both of them became opened . . ."
"And Jehovah God went on to say: “Here the man has become like one of us in knowing good and bad . . ."
So when one looks at the big picture, where exactly did Satan lie to Eve? Did their eyes not open? Did they not come to be like God in knowing good and bad as admitted by Jehovah himself at Genesis 3:22? And if you're going to accuse Satan of lying when he said they positively will not die (because they literally died centuries later), then can we not also accuse God of lying when he said they will die in the day of their eating the fruit (because they did not literally die in that day but lived on for centuries)? So show me how Satan has lied more than God. On the contrary, Satan's words to Eve have been vindicated!
Sometimes I get the feeling that the whole account in Genesis 3 was just a fable meant to literally explain the origin of clothing and being ashamed of nakedness (Genesis 3:7,10,21), menstrual pain and painful birth (Genesis 3:16), why men dominate women (Genesis 3:16), why most women are afraid of / hate serpents / snakes (Genesis 3:15), why serpents / snakes have no legs (Genesis 3:14), why we decompose into dust / are buried in the ground when we die (Genesis 3:19), etc; and some early religionists took it way too seriously by seeing it as real history and coming up with the idea that the Satan mentioned in other books of the bible was behind the serpent of Genesis 3. Note: Neither "Satan" nor "Devil" is found anywhere in Genesis.
