What you're saying isn't some profound conclusion; it's a cop-out to excuse a lack of thought.
EDIT: From a purely logical standpoint, there is no way to be 100% certain of anything. However, using the tools that we have (i.e., our senses and logical deduction), we can develop degrees of certainty about assertions that make certain conclusions more likely than others. A simple example: I see a computer in front of me. I can be as sure as possible that it really exists because all of the evidence possibly available to me (all of my senses agree, I have no reason to believe I'm hallucinating, etc.) agrees on that same conclusion. The same sort of logic (weighing the evidence) can be extrapolated to more complex problems, including the existence of a god.
