If you quote the Quran to me, it doesn't make any sense and so the objection becomes valid so you should ask yourself... Why are you quoting the Quran to me because I do not believe the Quran is from God. But when I quote the Quran to you, it makes sense because you believe it's from God so back to my main question again. Let's see if you answer the question or you will try to avoid it again.
So if you are in doubt, [O Muhammad], about that which We have revealed to you, then ask those who have been reading the Scripture before you. The truth has certainly come to you from your Lord, so never be among the doubters. Quran 10:94
That's Allah in the Quran asking Muhammad to go to the people of the Book ie. Jews and Christians for confirmation so even Muhammad had to go and double check with those who have read the previous scriptures. Have you read the previous scriptures? How much of them have you read? Where is the confirmation of Islam in the previous scriptures? Where in the previous scriptures does Jesus warn us not to call Him the Son of God? Where does it say that Jesus was not crucified or that someone else was crucified instead of Jesus? Where does it say that God is not our Father because if He was, then He wouldn't punish us for our sins? Where does it say that God doesn't have a Son and it's blasphemy to say He does?
