kiwidan,
re: "That's easy to address... She wasn't married, never been with a man, and had not yet even planned to have children..."
How do you know that she didn't plan on having children?
re: "She just said shes not married or been with a man so how is [she] going to get pregnant. Simple question."
Simple answer - she was engaged to be married. What reason would she have to think that she wouldn't have normal relations with her future husband ?
re: "If someone told me now I'm going to have a child, I would be like I don't have a wife so what are you talking about how is that possible.. Simple question."
Simple answer - Mary knew she was going to have a husband.
