Why were Adam and Eve cast out of Eden?

So given his powers and status as the creator of “the earth and heavens” (likely a Hebrew merism indicating “everything that exists”) including human beings, and being able to cause rain to fall down, does it make even sense to assume that he would ever feel “threatened” by human beings?

Secondly, you haven’t answered my first point, about the meaning of the term “LORD God”. Clearly if you want to understand this term properly, you have to understand the connotations that come with that term, which means studying the occurrences of that term in the entire book of Genesis at least, or better, the whole Pentateuch.

My point is that there is no “reading the story in its own terms” without consulting other sources of Hebrew literature, for these provide the context and meaning of the words used. The translators of the text into English no doubt also took these into account.
