There is A LOT of proof of God existing, like this topic! Also, there is faith, and all of the miracles that have happened over the years. Guess what, people think Jesus is NOT the Messiah, guess what, he is, how would he have risen from the dead? Also, how would he have kept all of these people fooled for all of these years? Can you answer that? No one has ever proven him fake from what I've seen. Also, like Einstein said, just because you can't see something, doesn't mean it's not real. (In the professor's logic) You can't see air, so it is not real. (End of professor's logic)
I just have to say, there is much proof out there, you you do not believe, I hope this helped you to believe.
