god exists?

Well that is a very deep question that you ask. In order to answer that question one must first understand that people need to have some feeling of meaning, and purpose inside of themselves. In doing so, god emerges. God is not just a spiritual character, but "the" is also what is in ones self, that motivates and encourages us to keep on living.

just look around you and think about the creation of the world you will realize that only god can make all those good things

I'm not religious, well at least I don't belong to a religious denomination, but I am a spiritual person. Anyway, it is my belief that all religions are a form of ideology and that God/s are not "imaginary" as such, but they are more of a belief than a tangible, touchable human being. I think that ours Gods etc are what we believe them to be and that it is a very personal thing that cannot be decided for us by someone else. =)

God does not need to physically be present for you to see the wonders that he has done and made. he made the earth and the son and what ever else you see every day. He created you in the finest detail. You can only see his beauty once you have completed your task on earth and rise to heaven.
