The first, most obvious, feature of Genesis 1 & 2 has to be that it is a celebration of God's creation - all of it. Before we get to the "male and female" bit, let's consider the rest.
On the first day, "God separated the light from the darkness. God called the light Day, and the darkness night." Does this imply that there is nothing in between? Of course not. There is twilight, there is gloaming. Night can be well lit by a full moon, day can be dull and cloudy. But still, there is night and day, darkness and light - which do not deny the existence of intermediate states.
On the second day, God "made a dome that separated the waters under the dome from the waters above the dome...and called the dome Sky". We know from science that there is not a "dome" above, as a fixed object, but we accept the existence of something we call "sky", even though we cannot say where precisely it begins or ends.
On the third day, God separated the land from the waters. "God called the dry land Earth, and the waters he called Seas." Again, we know from simple observation that this simplifies the picture. On the land there are also rivers and lakes, as well as marshes, swamps and deltas that are not clearly either wet or dry, or may vary in state with the seasons. At the coast, there are intertidal zones, which are land at low tide, and sea at high. On the oceans, there are arctic zones where frozen sea creates ice shelves, a form of "dry" land. Yet none of this negates the concept of a difference between dry land and sea - and the use of the concept does not deny the existence of intermediate states. Also on the third day, God created the plants:
Then God said, "Let the earth put forth vegetation, plants yielding seed, and fruit trees of every kind on earth that bear fruit with their seed in it." And so it was.
But where, in this description, are the plants that do not bear seeds or fruit? Are they not also part of creation?
On the fourth day, God said, "Let there be lights in the dome of the sky to separate the day from the night", and so he created the sun and the moon and the stars. From science though, we know that this does not complete the picture: what we commonly call "stars" include the real stars of astronomy (which in fact are all suns, like the one which is familiar to us, but vastly more distant), but also includes nearby planets showing only a reflected light, and galaxies so distant from us that to the naked eye they resemble single stars. At times, the sky also includes what seem to be shooting stars, meteorites entering the atmosphere, and comets. Here too, the reality of creation shows an abundance of forms beyond those included in the simple description "the sun, the moon and the stars".
On the fourth day, God created the animals. Here, there appears to be recognition of the diversity of life:
And God said, "Let the waters bring forth swarms of living creatures and let birds fly above the earth across the dome of the sky." So God created the great sea monsters and every living creature that moves, of every kind, with which the waters swarm, and every winged bird of every kind. And God saw that it was good.
Yet even here, the list is not in fact complete. By specifying the "creatures that move", what provision is there for the mussels and limpets of the sea that do not move, but cling to the rocks for stability? What of those living creatures we sometimes prefer not to think about, the bacteria and viruses? Are they not also part of God's creation?
