Ge 1:1 Inclusio
The inclusio of Genesis 1 is complicated because there is another pattern within it. Instead of a simple ABA pattern, it appears as ABCDABCDA.
There are apparently three A's if 'heavens' is defined as A. But if A is defined as 'heavens and earth', then the pattern is ABCDBCDA. The apparent middle A is not legitimate since it is forced; 'heaven' and 'earth' are mentioned but separated by other words.
The author tells the reader that the Final A points to the A in Ge 1:1 rather than the illegitimate A when he defines the final A; he points to the beginning A.
He describes the first A: "Ge 2:5 And every plant of the field before it was in the earth, and every herb of the field before it grew: for the LORD God had not caused it to rain upon the earth, and [there was] not a man to till the ground."
The illegitimate A is after the plants of Day 3 had sprung up.
