I agree in that I would never blame the X-Files for the existence of conspiracy nuts, but you can't seriously suggest that the world depicted in the X-Files doesn't have a much higher level of realism than Star Wars or Superman (in fact, people can immediately know that they do not live in Superman's universe because the existence of Superman is not a secret in-universe.)
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
Psalm 14, KJV revised edition
