You are begging the question since God can create life from nothing and has, so why would God bring a prophet into this world by virgin birth without accepting paternity for what He did?
Genesis 6:1-2
6:1 Now it came about, when men began to multiply on the face of the land, and daughters were born to them, 2 that the sons of God saw that the daughters of men were beautiful; and they took wives for themselves, whomever they chose.
NAS
Genesis 6:3-4
4 The Nephilim were on the earth in those days, and also afterward, when the sons of God came in to the daughters of men, and they bore children to them. Those were the mighty men who were of old, men of renown.
NAS
Job 1:6
6 Now there was a day when the sons of God came to present themselves before the LORD, and Satan also came among them.
NAS
Job 2:1
2:1 Again there was a day when the sons of God came to present themselves before the LORD, and Satan also came among them to present himself before the LORD.
NAS
Job 38:7
7 When the morning stars sang together,
And all the sons of God shouted for joy?
NAS
The angels are the sons of God, so why can't Jesus be the Son of God according to your faith? It seems Allah has not given you an explanation for the virgin birth so you denigrate God's record of who Jesus is and what He did on this earth.
