Why did God take time to specifically dictate chapter 2 of Genesis? The chapter is important. In that chapter He specifically says that Adam and Eve were created not like animals. They were created special (set apart, holy), in God’s image and likeness (good, intelligent, creative, etc), alive by the breath (aka spirit) of God. And marriage was created as a symbol for God’s relationship with the church, His bride. Those are immense theological and moral implications.
Also, when I read chapter 2 of Genesis, I noticed that God assigns Adam and Eve the practices of working and keeping the garden. And these terms are the same used in Leviticus for those priests that upkept the tabernacle and temples in the OT.
Genesis is about God's holy Temple, and Adam and Eve are assigned the objectives as his priests. And so the text is more theological about assigning these representatives as priests of God.
But I wouldn't view any of this as biology.
Adam of course is made from dust, but then again, all of mankind is made from dust in the Bible, Abraham says that he himself is dust, Job and the psalmist say that they are dust, Ecclesiastes, and passages in Psalms and ecclesiastes note that all of mankind is of dust.
And the dust returns to the earth as it was, and the breath returns to God who gave it.
Ecclesiastes 12:7
For he knows our frame. He remembers that we are dust.
Psalms 103:14
You hide your face, they are terrified. You take away their breath, they die and return to their dust.
Psalms 104:29
By the sweat of your brow you shall eat bread, until your return to the ground. For from it you were taken; for you are dust, and to dust you shall return.”
Genesis 3:19
Remember that you fashioned me like clay; and will you turn me to dust again?
Job 10:9
Then Abraham answered and said, “Look, please, I was bold to speak to my Lord, but I am dust and ashes.
Genesis 18:27
Your descendants shall be like the dust of the earth, and you will spread out to the west, and to the east, and to the north and to the south. And all the families of the earth will be blessed through you and through your descendants.
Genesis 28:14
So I don't think that Adam being made of dust has anything to do with biology.
And with respect to Eve, it says that she's made of the side of Adam, but we also noticed that Adam entered a deep sleep right before Eve was created, and in the Old Testament, deep sleep was associated with prophetic vision, so you might think about Abraham later on in Genesis, he enters a deep sleep and then he has visions from God. You could think about Daniel and Nebuchadnezzar, Nebuchadnezzar enters a deep sleep and then he has his visions.
This is a common thing in the Old Testament where individuals enter a deep sleep and then they have visions of things.
And when we look at the creation of Eve from Adam's side, immediately proceeding her creation, we see that Adam enters a prophetic visionary deep sleep.
And also the side, the tsela, this term here is used with respect to the tabernacle quite often, the north and south side of the Tabernacle, or the west and east side of the Tabernacle. So I would say it's better to interpret this as Eve being made not of a rib bone, but of a side in the sense that she is the north side to his south or she is the west side to his East. Adam is perceiving her as literally like a half of his body.
And so Adam says wow, bone of my bone and flesh of my flesh.
She's not just a rib bone, she is his mirror image.
But all this aside, I don't think any of this has to do with biology either.
