And there is another explantion for the seeming disparity between the two chapters concerning mans creation...
I have been lately watching a particular preacher on TV, name Arnold Murray...not saying that I believe what he teaches, but he teaches the following so far as I am able to make out...
That on the sixth day of creation, God created all the various human races...men and women...plural....
Then the seventh day God rested...
Then the next day, after the seventh day, which would be the eighth day, God then created the special Adam, the created the special Eve, from his rib...
Murray also will say, that this explains where Cain got his wife from...rather than buy into this oft offered explanation that Cain married his sister(thus committing incest), Murray maintains that Cain married a woman from one of these other pre-existing races....
He also uses this to explain how the diversity of races came to be after the flood...that altho Noah took on board his wife, his 3 sons, and his three daughters-in-law, he also took on board two of each specific human race...two blacks, two hispanics, two Native Americans, two Asians, and so on and so forth...Murray does say this explains the diverity of the races on earth today, as no one could possibly believe that all the races alive today, actually came from Noah and his family...
One can believe Murrays teachings or reject them...but they do present an interpretation quite contrary to mainstream Christian religions, and Murray does have a very large following in real life in his own church, and on his TV evangelical show...
So, there are various and quite differing interpretations in Genesis, all coming from different and varying Christian teachers...Murray does not appear to base any of his ideas on just pure whim...indeed he backs up everything he says, with Biblical Scriptures...
Each person can read, and decide for themselves...
For that matter, this may still be God's sixth day.
The prohibition against this came much later...
