Skepticism and Faith

Being a skeptic entails eing judgemental ( for lack of a better word) about pretty much even when these things could be scientifically or logically explained. To borrow wikipedia's definition of skepticism, "A skeptic critically examines the meaning systems of his/her time, and this examination usually results in a position of ambiguity or doubt. This doubt can range from disbelief in contemporary philosophical solutions, to agnosticism to rejecting the reality of the external world". This begs to question the fact that if they question everything and everyone and certainly ponder on the certainty of human knowledge then they must have a hard believing in history and most of all religion. I mean how can you believe something you didn't experience (no intent on invoking von Glasersfeld) or better yet faith in a supreme being whose existence (no pun intended) we can't attain either by our knowledge or our perceptions. Skepticism was first introduces by Socrates who claimed the only thing he knew was nothing; even that in itself is paradoxical ( because he says he knows nothing thus he knows something-the fact that he knows "nothing") but that if the topic for a different blog somewhere down the road. But back to the question of faith and skepticism. Do skeptics believe in historical events, do they have faith in God or any divine being or gods for that matter? What strikes me ass odd is the fact that skepticism's foundation is linked to the Greeks who to my knowledge were also very godly; from zeus, to atlas, thor and the rest. How can a skeptic justify his belief (if any) in religion and consequently his faith when he restrains from making assertions of things in everyday life; "The hallmark of the skeptikoi (the Greek terminology refered to skeptic philosophers) was caution; they refused to be caught in assertions that could be proven false". ?
