It's somewhat confusing, but, I think you meant for your note to continue from the title...So I'll just assume you meant to write this: "I'm an atheist, but I do believe there's a god above us,so what am I? But, it's not a god that christian, muslim or buddhist demonstrates(demonstrate?). The God is something beyond us, never meddle in our business, just set the rule and doesn't care about us." Here is a complete correction: "I think I'm an Atheist, but, I also believe there is a god above us...What does that make me? He's not the Christian god, the Muslim god or Buddhist god. The god I believe in is something beyond us. He never meddles in our business, he never cares about us, he just sets the rules." Note: A god (unless you are talking about a specific one) is generally considered an "it", that being said, in most writing and conversion we refer to god with the masculine "he".

Atheism is the rejection of belief in the existence of any gods. Atheism is contrasted with theism which is the belief that at least one deity exists. So you might call yourself "a theist."

Atheism - as the name suggests (it originated from Greek "atheos", meaning "no god"), it is a belief that there is no god. Judging from the description of your beliefs given in your post (especially the last sentence), I think you could be called a deist. "Deism holds that God does not intervene with the functioning of the natural world in any way, allowing it to run according to the laws of nature". http://en.wikipedia.org/wiki/Deism

There is a term for this called "Agnostic" http://www.thefreedictionary.com/agnostic

An atheist is one who doesn't believe in a "god". You are a Theist. Which is one who believes in the exitence of "god" or "gods". - Religous people can be theists, but there god is specific. Theist is just a general term.
