In the minds of the delusional...
there is no limit to our ability to alter the truth. 9-11 was a USA/Zionist plot. Any evidence to the contrary is faked. Now those grainy UFO films, there's some real evidence
When we arrive at Cydonia there will be some that will swear the CIA got there first and move the face to area 51.
And some will deny any proof of weapons in Iraq simply because it suits their politics. They are worse than the Cydonuts.
