We cannot say with certainty that aliens exist, but we can say with certainty that the probability of them existing is vastly superior to the probability of them not existing.

Maybe...maybe not. We don't really know the probabilities involved. Anyway, that wasn't really my point. My point was that we can actually have meaningful discussions about non-observed entities.

Not familiar with the Drake equation?

I think you might be confusing confirming something exist through evidence and something existing in of itself. For simplicity sake let me use myself as an example:
If there were no internet and there was no profile on vgchartz called cyberninja45, you (dsgrue3) would not be able to confirm that there actually is a person that is capable of typing this response, but your inability to confirm my existence (through the internet) does not negate my existence for 20 something years on the earth.
In other words I still existed whether you had evidence or not.

Uh, you can't use self-existence. That's redundant. It will always be true and isn't a valid hypothesis.
Indeed, existence is absolutely predicated upon evidence! That's what I said!
Your anology is ridiculous, the moment you were birthed someone witnessed that event, thus confirming your existence. Thus you exist.
