Belief

If you accept the premise that concentrated belief can create physical manifestations (ie: the concept that man begat the gods by believing in them) does that mean that things like Area 51, the Illuminati, the Hollow Earth, and the pregnant vampire elvis clone from the tabloids just might be real too?

I wonder...

(I should probably note that I'm in the midst of reading American Gods by Neil Gaiman at the moment, or else people will think I'm totally nuts.)
