What's worst: god, horoscope or homeopathy?

Yes, no, maybe, 42

Would people class alien conspiracies as "woo"? I don't think I would, because it's not an appeal to the intangible, but rather to the improbable. I don't mean like we're all aliens or something, but just that aliens have landed here and stuff, and we've taken their ships and hid them. All that. And abductions, I suppose.

I don't know if they're "woo", but there isn't a shred of credible evidence for such events having happened. Conspiracy theories are self-perpetuating fantasies, where we're supposed to accept special pleading when it comes to material evidence, because lack of such evidence (or existence of evidence to the contrary) is part of the claim.

It's impossible to prove a negative. Therefore we can't definitively prove aliens aren't secretly visiting Earth. But that doesn't mean we have to take seriously claims, that technologically superior beings, with an ability to detect life/intelligence from very far away traveled inconceivably large distances, only to play proctologists with drunken vagrants, or mutilate cattle in ways small scavengers would... No more seriously than any other legend. 

I think the government is hiding the evidence of the existence of pixies. I know it's currently not the most fashionable "theory", but it's pretty much equally plausible and un-falsifiable as those new-fangled "alions" kids are talking about these days...
