To me these changes were made to get to the idea of a monotheist belief. Only one god. Elohim means gods plural and I believe the original texts says Elohim not Angels or sons of Israel.
Genesis Ch.3 : 22 ...."here the man has become like one of us in knowing good and bad "
The fact that God said the man has become like one of us is telling.?
God is actually saying he has peers ,beings the same as he is , God`s.the same as he is.
And Adam having that Knowledge now of good and bad put him on the same level in that sense of the Gods that then existed at that time.
Not that he had the power of God but that he had the intellectual ability of knowing Good and bad right and wrong ,evil and good.
