Nice thread Smiddy! We can explore some concepts here, Associated with the concept of Paradise is the concept of the tree of life. Chrisstian seldom talk about the memes that neighbouring societies (to Israel) also had.
A meme is _ "an element of a culture or system of behaviour passed from one individual to another by imitation or other non-genetic means."
Once you realise that, its easy to understand how these 'memes' got talked about among the Israelites. Now a close by human society that we know a lot about is Egypt. IN FACT,.though the bible doesn't talk about it, the Egyptians ruled over the Palestine area for a few hundred years.
Even the Israelite hero Moses, it seems knew all about Egyptian culture ) Acts 7:22 - "And Moses was instructed in all the wisdom of the Egyptians," (English Standard Version)
Now think about this image:

It portrays the Egyptian concept of the 'Tree of Life." Was this Egyptian meme transferred into Israelite culture? Two dollars say it was!
But even if you want to argue that Moses wouldn't do that, lets's go to another nearby culture that also held Israel in subjection for a time.
Here's another image.

This is an Assyrian 'Tree of life,' and look whose guarding it? Heard that before? Yup, If you want to think about this, read Genesis 3:22 and wonder how the scribe heard this meme.
Again, we have a powerful empire, Assyria and later Babylon, ruling over the Israelites and their memes being transferred into the subject state of Israel.
