His proof is the quran..when you study islam well and accept it .you will believe in everything in it..and for jesus christ not being a god it's just made sense.. why god came in human body and sacrifice himself for the salvation of humanity .. he can just say i forgive you .. and you found it weird that the prophet Muhammad talk about jesus after 600 years but you don't find it weird that god waited thousands of years until he decided to send his son or himself "whatever" for the salvation

Every prophet came with prophecies that were suitable for their time.. in the time of Muhammad pbuh, this was linguistics, poetry and writings. He came as the seal with a final book which was perfect from cover to cover, no mistakes normcontradicfions and a guidance for all of humanity. Funny thing: if you look up mistake advocated by christians, debating with regular people it seems like there might be contradictions or errors.. but even those are easily explained by students of knowledge.

You can check in the bible, there is not once Jesus says that he is a God.. but there are many explanations that he is a teacher and a human.

The logical of fallacy of course. How can the 600 years evidence gap, revised a well known bible across the Asia & Europe? According to logic, that's very unlogic.

Jesus used to pray ? If yes, there was some entity worthy of being prayed, thats God. He was a creation not a creator.

Did you know Mohammed and Jesus had the same father?
