Here we have a new twist in the UFO-ET-DISCLOSURE mythology. As you know, each one of the show men and women must fight against the NHS , Nothing Happens Syndrome. So they must find new elements to keep people (a very few) interested. Songs are OK, or The Pope ready to reveal the ET presence, or Conspiracy theory, and perhaps the new clowns in the Circus, the Exo or hyper or extra dimensionals.
Remember dear friend the fundamental Galactic Law...The show must go on.
