IS the government withholding information about UFOs and area 51?

I believe the government is hiding information from us. which is against the Constitution which clearly states that we the people have a right to know. I also think the government is attempting to cover their es by surfacing false information such as in the Roswell siting when they released a statement saying that it was a UFO. Then a week later that said it was only a weather balloon. I also believe that area 51isn't the only government facility hiding information and UFOs. I don't believe that the strange things people see in the skies are weather balloons or government aircraft. I also think as U.S. citizens we deserve the right to know and the government is being unconstitutional by withholding information from us on things that could one day effect us in a bad or dangers way.
