Yeah sure. And God looks us from the top of the clouds, and during christmas night ol' Santa Claus brings presents to children, and when you're dead you don't simply rot but go to Heavens. Excuse me, but I haven't ever seen a tiny part of the shadow of the tail of an evidence of any of these (and yes, I've seen UFOs but I don't pretend them to come from Alpha Centaurii until I know better, I just don't believe, I'd rather know you see?).
update Sorry, I don't try to take it easy with your beliefs, friends, because I simply can't stand "political correctness", it's way too close to hypocrisy. But feel free to send me any proof :)
you simply should dig deeper, it is possible to seperate hoaxes from real items. yes most ufos are human-made but not all. even in the 70*ies the IBM material researcher Dr Marcel vorgel was gaven metal samples from ufo case of billy meyer. before camera he statet that he cant reproduce that material because it should have been assembled in some sort of cold fusion. and that was only one piece of puzzle of too many to make a joke of this subject.
