The term "Abrahamic mythology" is simply useless. You seem to instinctively acknowledge this when you talk about terms evolving.Are you truly monotheistic?
Please just relax and think about this with an open mind. Abrahamic mythology has an entire pantheon of spiritual beings who are believed to exist Above and Below and Within in a manner beyond our comprehension. In the Abrahamic religions, the term "god" seems to have evolved to mean the ultimate being of ultimate everything... when before, the roles of many gods and goddesses were more comparable to the roles of many of the angels and demons we learn about in Abrahamic lore.
I am not a polytheist and would argue that much of Genesis 1 and 2 is a polemic against polytheism presented in the language of the day.
