Why don't you believe in GOD? Have you ever tried to honestly look for GOD? One needs to put effort to attain even a small amount of knowledge, and you want the knowledge about GOD to be handed to you? Only those who are willing to go down this path will ever achieve this knowledge, but to even get on this path you have to have a belief first, you can't go looking for GOD with a closed mind.
Now I can understand people being put off by various religious versions of GOD, or the various religious practices, but that doesn't mean you entirely reject the concept of GOD. One needs to be able to separate the GOD from religion. One will never find GOD using his mind, the logical/ rational mind will always be a hinderance to the path of spirituality, there are things a mind cannot comprehend, the mind always wants to breakdown things into smaller units to understand them, the mind is always distracted by this materialistic world, that's why the mind can never understand GOD.
The GOD that I believe in isn't some supernatural being with human-like features, who's sitting there listening to our everyday problems and solving the problems of those who pray to him. This universe is already working on a set of laws, the laws apply to every being, we are all responsible for everything that happens to us, GOD is not going to interfere on our behalf to solve our problems.
If anyone still finds it difficult to believe in the idea of a GOD, the least they can do is read about buddha, I mean Buddha has really broken down this knowledge into simple rational/logical concepts, simple enough for the rational mind to understand.
