Is the government hiding evidence that alien and ufos and monsters are real?

Now, let's get serious. There are no aliens known to exist, just a bunch of anecdotes, and no matter how high you stack anecdotes, they never become evidence. We hope there is other life out there, and we consider it likely. But someone has to be the first form of intelligent life in the universe, and there is no evidence that it isn't us.

Yes, people including me believe that the government is hiding all the evidence of there ever being UFOs or aliens. All the evidence are maybe hidden in the top secret facility Area 51.

The problem is that the people who believe it, never prove it. The US Government covers six percent of the Earth... where are all the saucers that crash elsewhere? "The government ate my homework" is a really lame way of saying "I have no idea whatsoever how to prove what I want you to believe".
