See my later reply to the parent comment, but basically, first there's the creation of the whole world and all the peoples in it, then there's the creation of the Garden of Eden and Adam and Even and so forth. The first is ascribed to "God", or "Elohim" in Hebrew -- a plural word which has recently been awkwardly recontextualized through a monotheistic lens, but probably originally meant "the gods" -- while the second is ascribed to the "LORD God", or "YHVH" in Hebrew -- a definitely specific God.
