Yo geeze, did you want to remind him of where Adam gets his humanity or should I? One of us could also throw in the part about "God can of these stones raise up sons of Abraham".
I'm not saying God couldn't do it as you suggest. If God had wanted, He could have formed Jesus out of clay(dust, dirt, etc.) as He did Adam. But He didn't. He formed Jesus by the Holy Spirit 'overshadowing' Mary and having her conceive Him in her womb.
Didn't you check out Galatians 4:4? It says Christ was born of a woman. Note one of the scriptures you use is the one from Matthew where Jesus says "Verily I say unto you, Among them that are born of women there hath not risen a greater than John the Baptist: notwithstanding he that is least in the kingdom of heaven is greater than he."
John the Baptist was born of a woman and Jesus was born of a woman. Why do you labor so hard to deny Scripture?
