The man called his wife’s name Eve, because she was the mother of all living.  (Genesis 3:20)

When God created Adam and then for him a helpmeet, the woman, they were under no immediate obligation to procreate.  They were perfect in every way and there was no disease.  Adam and the woman would represent humanity and be undying.

Eternal beings are then created and nowhere in the Bible do the angels procreate; rather they are brought into being as celestial host and endure.
