The problem with the "We don't know what we don't know" claim is that it is really irrelevant. We do not know much for certain, and is doubtful that we will ever know much with an absolute certainty. However we can deduce probability based upon current knowledge. We have not found evidence for the existence of leprechauns, we cannot say that leprechauns do not exist, but it is a safe assumption based on what we know. Every case of magical beings or otherwise supernatural phenomenon has been debunked, so anything that falls within that category doesn't exist until it is thoroughly demonstrated otherwise.
"In our youth, we lacked the maturity, the decency to create gods better than ourselves so that we might have something to aspire to. Instead we are left with a host of deities who were violent, narcissistic, vengeful bullies who reflected our own values. Our gods could have been anything we could imagine, and all we were capable of manifesting were gods who shared the worst of our natures."-Me
"Atheism leaves a man to sense, to philosophy, to natural piety, to laws, to reputation; all of which may be guides to an outward moral virtue, even if religion vanished; but religious superstition dismounts all these and erects an absolute monarchy in the minds of men." – Francis Bacon
