And Adam called his wife's name Eve; because she was the mother of all living.
Genesis 3:20
"God could have created a mother to take care of the baby.
Q: That is true, but where would she have come from? In other words, the obvious answer
to this problem of the logical point for the commencement of the great cycle of
living organisms is the adult.
A: And so God created Adam suddenly, as an adult, and
Eve suddenly, as an adult—by purely supernatural methods not observable in
our present world.
God’s creative plan introduced adult human beings fully
capable of 
bringing forth their own children and caring for them as today.
The Bible, then, does shed light on the question of which came first, the hen or
the egg. Obviously God created the hen first, capable of laying her own eggs and
hatching them. And thus the cycle of life began with the adult: full-grown fruit
trees, adult animals, Adam and Eve." CMI
