No, and atheist.
About agnosticism...
Any reasonable human being should know that the existence of a god can be neither proven nor disproven. But are we all agnostics? No, because some people think the existence of a god is near certain (theist), and others think that there is next to no chance (atheist). I see agnostics as a theist questioning their religion, a weak atheist, or someone inbetween.
