Sin, which passed down to all of human kind through Adam, passed to all man. "Therefore, just as sin entered the world through one man, and death through sin, and in this way death came to all people, because all sinned, Romans 5:12" The Bible tells us all men are sinners because Adam was their father. Adam, as you know, was Cain's father. Therefore any child Adam fathered would be at the least a 1/2 sister or close relative. There's no getting around it. What you are suggesting would require a different father than Adam, which clearly wasn't the case. And such a person would never have died since death came through sin and sin through Adam, so we could still discuss this with him today. Obviously untrue.
