I wouldn't classify myself as either, I just think it's funny how "argument from ignorance" is often used as a tool to "prove" one side or the other correct in debates like these, with the side using it blissfully unaware of the irony. To clarify, I'm not talking about Neil deGrasse Tyson or the video itself, I'm talking about the way in which the poster of the video appears to be wielding it.
As it pertains to the video, I'm sure Tyson is affable and entertaining as always, but I can't imagine his response to such a question ventures very far beyond the boundaries of common sense.
My feeling is that space is far to vast to believe we are the only "intelligent" beings in it. If nothing else, there's no proof on either side of the debate, so I'll just say that I wouldn't be surprised to find that there were infact E.T.s.
