The 'you've got no proof' meme -- 
and that's all it is is a repetitive mind meme to con people 
into believing there is no proof. 

From: Laughing Last (sss@sss.sss):

Don't you ever tire of pumping the meme 'you've got no proof' into the
newsgroups?

Of course there's proof - proof positive, sitting 7 floors underground, ware
housed at area 51.  The military is scared shiftless about it too, because they
can't reverse engineer the alien saucer and they don't want to admit to the
population-at-large that in *THEIR* opinion, the aliens are not only unfriendly,
but cruel as well.

And that information, should it become widely known and understood, would surely
cause panic, because the government nor anyone on earth can stop these aliens
from abducting people, kidnapping children and experimenting on them against
their will.

The proof is at Area 51.  You know that, the government knows that, and I know
that. So what's the real problem, eh? I'll tell ya...Aliens are hostile to
humans.
