Maybe you should take a look at the Sumerian Tablets which was the original Genesis that the Bible account was taken from.<quoted text> I think, most assuredly, that you misunderstand the kingdom of heaven quote from Luke.
Wanting to "be like God" was the fall of mankind, Genesis 3:5
The first symbols of serpents were attributed to Enki and then Ninhursag. However, the story of the serpent becoming an evil symbol began with the wars between Enki and his brother, Enlil.
This story later was reflected in Cain and Abel, and all the stories throughout your times of brothers competing for power, favoritism and inheritance. Enlils anger with Enki caused him to twist the truth around to make the serpent evil, which later became what you know as the story in the Bible. What you think of as being Satan is not that at all, but THE REVERSE!
In the Garden of Eden situation, Enlil was furious that Enki permitted humans to have access to knowledge, the mixing of the Anunnaki with human genes, thereby becoming more "godly," and equal to the Anunnaki. To strike back at Enki, and in the attempt to regain his power over humans, Enlil vowed to tarnish Enkis reputation by spreading the idea that the serpent of wisdom was evil. Enlil tried to wipe out knowledge of the DNA coding Enki gave humans, and of what the Anunnaki used in order to have longevity (gold).
