Adam and Eve were his parents.
Only Adam and Eve had no parents in the Bible. Adam was formed of the earth and Eve was formed from one of Adam's ribs. The wives of Abel, Cain and Seth came from the land of Nod. Their parents are not specified, but they were not related to Adam and Eve and there had to be a pair of their ancestors who had no human parents. From Adam and Eve's children the world was populated. The only "Immaculate Conception" was Jesus Christ of Nazareth. He was conceived with no father but still grew in Mary's womb. So technically He had a mother and God would be considered the father dependent on how that conception took place.
No, there was only one Eve, the original Eve that God created as a companion for Adam in the Garden of Eden. There was no other Eve before her, hence the term is used that Adam and Eve are the Parents of all Man kind.
Adam and Eve were made out of earth and clay etc., therefore had no biological father. They were our first 'created' parents by God.
