(1) its more of a process(way of nature) and he/she don't create their child. They give birth by some system(or way), which God had made for us.
So if God gave birth then it means, God is not the only God but there is another God over that God( who made that nature). But if the God created His son then the child is not His son but he is the creation of the God.
So I believe it's impossible for a God to give birth. And Jesus must be the creation of God and not the son of God.
I didn't mean to be offensive but thats my question.
(2) Secondly, God and human are two entirely opposing(opposite) things. One is the Creator, other is His creation; One is eternal(never dies), other is mortal(he dies); God is perfect, man is imperfect. and there is a long list
So the point is.. How can be somebody be alive and dead at the same time? How can somebody be the creator and created at the same time?
Its impossible that Jesus was God and human at the same time. How can He be the son of God and son of Marry( human) at the same time?? If God had to become human than he can't remain God any longer.
