UFOs do exist. They are found in Renaissance art, on ancient coins, etched on cave walls--and even reported in the Bible.

They supposedly aided George Washington in winning the American Revolution. UFOs were also reported flying over Normandy on D-Day, and were dubbed "foo fighters" by World War II pilots. In Vietnam, an Air Force commander said they were "plagued" by UFOs. Even today, the reports continue to pour in, as noiseless objects are seen darting over the battlegrounds of the Middle East.   These sightings, as inconceivable as they may seem, are made by high ranking officials, soldiers and news reporters.
