"Have We Ever Been Visited by Extraterrestrials?" Unfortunately I probably won't be attending the upcoming Lolita Bar debate, though I expect it will be interesting. As if often the case, interpretation of the debate question's wording makes a difference; who are "we" and do we really mean "ever"? A starship passing by while Australopithecus was foraging strikes me as less hard to believe than some scenarios.
A later debate will cover the supposed conundrum of whether Obama is a natural-born citizen. I would find that interesting only if it turns out aliens stole the long-form birth certificate.
