Hey cybex how about you get a clue about what you're talking about before you talk about it? nice grades in school but it seems like you need a reading lesson.
Agnosticism means by definition that you think the existence of a god is unknown and unknowable.
Atheism (more accurately nontheism) means that you are not a believer. It's more accurate to say that atheists are simply not believers, rather than saying they are disbelievers. However that's not the point. You see agnosticism as a different level of degree in comparison to theism and atheism, like there's atheism, then there's agnosticism, which is in the middle of theism and atheism, and then there's theism.
The terms atheism and theism refer to your beliefs, the term agnosticism refers to what is knowable and unknowable. You can be an agnostic atheist (meaning you don't believe in a god but still don't think it is knowable whether a god exists or not) or an agnostic theist (you believe in a god but you don't think you can know he exists with absolute certainty).
We are both agnostic atheists, because I don't believe that ANYTHING can be proven to be non-existent with absolute certainty... well maybe some things but not this. So stop using terms differently like a prick.
Theism is just like a boolean. There's only true or false, no undefined or shit. If you're not a believer, then you ARE an atheist, whether you're an agnostic or not.
