I am sorry but I disagree with some of the comments proving that god exists. If you read the bible, it says to have faith. So why are we looking for proof when we just need a little faith? There can not be a simpler answer than that.
The Bible doesn't say to have blind faith in God's existence. Rather, it says to have faith in the things that He tells us.
We all know in our hearts that God exists. Science simply proves it scientifically. Faith is faith in the things that He tells us, especially about Jesus salvation.
