Is it just me, or is the opinion that we're alone in the universe one of the most presumptious things humanity has put faith in? Personally, I believe that there are other life forms out there somewhere. I don't know if they visit us and steal inbred Americans to shove stuff up their ass and return them, but I believe that "we are not alone".
As for the Loch Ness Monster/Bigfoot/etc-I'm really not sure. Yeah, a lot of the supposed evidence is faked crap, but the idea still existed before that. With "Nessie" especially, I think that something is probably in there, be it a prehistoric dinasaur or just a deformed whale, I believe that there is something...
As for ghosts, who knows?
What about you, Rob?
