Such thinking has always amused and confused me. I'm surprised that people will so willingly believe that their government is capable of such vast conspiracies and coverups, yet that same government couldn't get Bradley Manning or Edward Snowden to keep their mouths shut, or keep the indiscretions of some hard-partying Secret Service agents off the front page, or keep Monica Lewinski quiet, or coverup Anthony Weiner, or Eliot Spitzer, or keep a hundred other embarrassments under wraps. Yet you'll believe that that same government has evidence of alien life visiting Earth, and (for some bizarre reason), doesn't want us to know about it? That they displayed unprecedented multi-level/multi-agency governmental cooperation? And has been successful at keeping such a secret for decades? With no one talking? No jilted contractors, no loose-lipped scientists seeking fame and notoriety, no incompetent fools accidentally leaving some evidence exposed, nobody with a guilty conscience, no deathbed confessions ... nothing.
I'm inspired by your desire to remain fooled.
So you conclude they must be lying? While you may lack the intelligence and education to double-check their findings, surely someone else out here must be able to sift through their data and either confirm it or expose it as bunk, don't you think? What possible purpose would they have for launching such telescopes into space in the first place, and then completely faking all of their results?
Isn't it instead far more likely that these simple scientists are simply doing what they've always dreamed of doing, and exploring the cosmos? Just because you can't understand the (admittedly advanced) physics they're using to make these discoveries doesn't mean it's not possible.
