Because God has not mother. God is the creater of all therefore needs no mother. Jesus was not God, he was the Messiah, a propthet of God.

It was not the mary of the Bible that claimed she was the mother of God. It was the mary of the catholic church which did that. The mary of the catholic church is very different than the mary in the Bible.
Mary in the Bible was a sinner. Mary in the catholic church was sinless.
Mary in the Bible was human. Mary in the catholic church is a god.
The mary the catholics worship is not the mary that gave birth to Jesus.
