aqwsed12345, you are arguing that John 1:1 states that Jesus is God and many people believe that Jesus is God because of that. That was written 65 years after Jesus died.
What did people believe prior to that? During those 65 years?
And why did John write the prologue?
Nowhere in Acts does it teach that Jesus was God. Infact it teaches the opposite. Stephen saw Jesus at the right hand of God 7:56 just like it says in Ps 110:1. In Acts 2 Peter states that God resurrected Jesus.
Did John write 1:1 because Stephen and Peter were wrong?
The book of John was a biography of Jesus. It starts just before his baptism with John, after his baptism with the calling of his apostles. then chapt 2 with his first miracle.
You see, John wrote the prologue to tell the readers that this Jesus was not some dude with charisma doing magic tricks. He had a divine existence before his birth. John did not state that Jesus was the God that they knew as Yahweh, because John 1:4 says "So the Word became flesh and resided among us, and we had a view of his glory, a glory such as belongs to an only-begotten son from a father". The Word became flesh, not God became flesh.
