Genesis 3:20 (KJV)

And Adam called his wife's name Eve; because she was the mother of all living

As more humans were created, and Eve is described as the mother of all living, how can this be? God created more females and males. Why wasn’t Adam the father of all men?

Is the same design used as Eve’s. Is this a cell biology statement and all women share Eve’s cytoplasm (Offspring inherit cytoplasm just form their mothers). Is this a genotype statement  concerning X chromosome consistency?

Kerr also hints that that the creation may even continue until Noah? I appreciate this will be controversial to many but it is backed by scripture, see this site Gap Theory in the Bible.
