Your mother being a mother of a human is correct, but your mother being a mother of human is incorrect. Can you tell the difference?
Yes, the difference is that the latter definition is a false definition of what a mother is. You seek to ascribe the same traits of God the Father to how we explain Mary to be the mother of God, the Theotokos. This is not how we explain mother of God.
1) The Holy Trinity is the Creator of all things. God created Mary.
2) Mary did not create God.
3) The Father begot the Son before all ages.
4) The Father and the Son are both co-eternal, uncreated, immortal, and fully God, as well as the Holy Spirit.
5) The Father did not give birth to the Son like women give birth to their children. He begot the Son, but there was never a time in which the Son did not exist. This is a Divine mystery which cannot be adequately captured with words.
6) There was a time in which the Word of God was not made flesh.
7) There was a time in which Mary was not alive.
8) When the Word of God became flesh, that is, fully human, He retained His divine nature. Thus, He is fully man and fully God.
9) The Word of God was born of a virgin, of Mary.
10) Mary gave birth to JESUS, the Son of God.
11) Mary was the Mother of God.
12) I have nothing else to say... I just wanted twelve points for the twelve apostles.
