The whole Adam and Eve story is just hilarious. Adam and Eve were the first two people on this earth. They then had two children, Cain and Able. Cain and Able then went to another city to find wives.
Where the hell did the wives come from?
In one version of the Holey bibble it tells where the sons of Adam found their wives in the "Land of Nod."
Now, Can anyone remember as a small child being told by your parents, "It's time for you to head off the Land of Nod," i.e. Go to sleep, I can btw.
So, and excuse the crudity here, could not this " Land of Nod" possibly be merely a quaint, clean bibblical way of saying that the sons of Adam being told to have and enjoy 'wet dreams' since they would have been quite virile and mature young males by then?
They had a lot more children, the two brothers are the only ones that have names cited.
So basically according to cults of YHWH the world was populated via incest... Twice.
A nice interpretation for this history, if you imagine a bronze age person, is thinking that the Eden is the tribe.
The tribe means life, you can grow, your culture your small world. It will provide, it will take care of you, all you need is there as long as you are connected. The tribe is the tree of life.
But once you want to go out and know what lies beyond the tribe territory, then you have to live by yourself, work for your food and be afraid to die at anytime. The the tree of knowledge is this separation from the tribe.
And once you take the fruit from the tree of knowledge, you cannot take the fruit of the tree of life anymore, otherwise would be easy to loose all young going to adventures and receive back crippled old people that came back as failures.
Xtions have their own side stories (like islam hadiths) and Cain supposedly left with a sister to start one of the mainly non Jewish Mideast groups.
It would be hominidist to refuse the delights on offer.
The wives came from another city, like you said.
As the bible states, God made the heavens and earth, the animals and trees, and therefore cities, towns, villages, hamlets, roads, drainage, wine, markets, healthcare, schools, civil service, metallurgy, and so on.
