Well, the first one is not a surprise...

...but where is the second one came from? Just because I answered NO to any question that presumed believing in God?

You scored as agnosticism. You are an agnostic. Though it is generally taken that agnostics neither believe nor disbelieve in God, it is possible to be a theist or atheist in addition to an agnostic. Agnostics don't believe it is possible to prove the existence of God (nor lack thereof). Agnosticism is a philosophy that God's existence cannot be proven. Some say it is possible to be agnostic and follow a religion; however, one cannot be a devout believer if he or she does not truly believe. </td> agnosticism 83% Satanism 71% atheism 54% Paganism 50% Buddhism 50% Hinduism 21% Judaism 17% Christianity 8% Islam 0% Which religion is the right one for you?

How you can be a Satanist without believing in God? Except for this one slip, I'd say a pretty realistic quiz.
