There are enough logical problems without bringing science into it. Did you ever wonder, for instance, how they can trace Jesus’ lineage back to King David through Joseph considering it was a “virgin birth”? But this guy would probably say Hid can suspend the rules of logic just like he suspended the laws of physics so that the earth stopped turning on its axis without catastrophe.
From Pope Benedict's book "The Infancy Narratives":
Joseph is the legal father of Jesus. Through him, Jesus belongs by law, "legally," to the house of David. And yet he comes from elsewhere, "from above"--from God himself.
