It's obvious to me that most are unwilling to even consider the existence of UFOs as a valid possibility in the face of even hard evidence. People are so trained to believe that UFO's are a hoax, and this is further reinforced by idiots making stuff up and doctoring photos that it's destroyed all credibility this theory may have ever had. Short of the president and government coming forward and ackkowledging that they do exist and full admittance, nothing would convince the general public otherwise. I consider myself to be an objective person, and consider evidence, and not to make assumptions. However some people are as unwilling to acknowledge even the possiblity of their existence as religious people are unwilling to acknowledge that god may not exist. Real physical proof presented to the public by the government. That's what it would take. Nothing less.
