Does God Exist?

I believe in God. I went to a catholic elementary school, and was brought up as a catholic. I don't attend church regularly, but I do attend on holidays like Christmas and Easter. I believe in the bible and all the Christians stories about God and Jesus. I also believe that God is the only god and creator of the earth. Some times I question why God lets bad things happen to good people, but I believe that everything happens for a reason and that God has a plan for all of us.
