Muslim proof of God in the form of written words and the Muslim name of God

I am trying to understand Muslim belief about words of the Koran written as calligraphy. Could you tell me if the following statement is correct? Many Muslims claim that the proof of God’s existence is literally provided in the physical form of the words of the Koran when they are properly written using calligraphy. In other words, their reasoning is: 1. The forms of the written words of the Koran are actually proof of the existence of God. 2. Since the physical words prove the existence of God, God must exist. I am also trying to clarify the Muslim belief about the name of The Creator. Could you tell me if the following statement is correct? There is no universal agreement among Muslims about the name of God and Muslims believe that God has the 99 names used in the Quran, known as ‘the 99 Names of God’. However, the most commonly used name is probably ‘Allah’, which is Arabic for ‘the God’.
