Why is the Virgin Birth Not Accepted by Jews

Why is it that the Jewish people…who believe that God created the earth and everything in it (from nothing), flooded the earth, talked to Moses through a burning bush (that did not burn up), delivered the plagues in Egypt (except protected the Israelites), parted the Red Sea (which defies the laws of physics), and countless other miracles (which no one can explain naturally), find it impossible to believe for God to have a virgin woman impregnated without a man?
