Genesis 2 treats us with a more ground-level view of creation and fills in some of the details from Genesis 1.  More specifically, we get a more vivid account of the creation of man and woman, and we get a good picture of the Garden of Eden, including some geographical clues as to its location, if Eden was in fact part of our realm.  Somewhere near Mesopotamia it seems.  The Sabbath is also introduced, though not given as a commandment yet.
