Order of creation
Here is the order in the first (Genesis 1), the Priestly tradition:
Day 1: Sky, Earth, light
Day 2: Water, both in ocean basins and above the sky(!)
Day 3: Plants
Day 4: Sun, Moon, stars (as calendrical and navigational aids)
Day 5: Sea monsters (whales), fish, birds, land animals, creepy-crawlies (reptiles, insects, etc.)
Day 6: Humans (apparently both sexes at the same time)
Day 7: Nothing (the Gods took the first day off anyone ever did)
Note that there are "days," "evenings," and "mornings" before the Sun was created. Here, the Deity is referred to as "Elohim," which is a plural, thus the literal translation, "the Gods." In this tale, the Gods seem satisfied with what they have done, saying after each step that "it was good."
The second one (Genesis 2), the Yahwist tradition, goes:
Earth and heavens (misty)
Adam, the first man (on a desolate Earth)
Plants
Animals
Eve, the first woman (from Adam's rib)
"So God created man in his own image, in the image of God created he him; male and female created he them"
Genesis II...God creates Eden, Adam, and Eve.
Seems rather clear to me.
It also answers the question of just who Cain married.
