Are governments hiding evidence of aliens? What do the records show?

Governments do keep things hidden, and the U.S. government once hid facts about UFO sightings. But no public evidence so far shows that any government is hiding alien craft or alien bodies. Those are two different claims, and this page takes them one at a time.

People who ask this question are not being silly. They often know real history. In the 1950s and 1960s, the U.S. flew spy planes that pilots and the public reported as UFOs. A 1997 history published by the CIA says the Air Force made misleading statements to the public to protect those flights. When people learn that, it is fair to ask what else was kept quiet.

Roswell is the best-known case. In July 1947, a rancher found strange debris near Roswell, New Mexico. The Army air base at Roswell first announced that it had recovered a “flying disc.” Soon after, a general said it was a weather balloon. Decades later, the Air Force said it was a balloon after all, but not a weather balloon. It came from Project Mogul, a classified program that used high balloons to listen for Soviet nuclear tests. So the first public story did leave something out. What it left out was a spy program, not a spaceship.

The modern claims are bigger. In 2023, a former intelligence officer, David Grusch, told Congress under oath that he had been told of a program that recovers crashed craft. He said he could give details only in a closed session. In 2024, the Pentagon’s office for unidentified objects, called AARO, reported that it found no empirical evidence that any such program exists. NASA’s own study team found no conclusive evidence in the scientific literature that UAP come from beyond Earth.

So here is the honest summary. “Governments keep things hidden” is Established. “They are hiding alien craft or bodies” is Not supported so far. New, checkable evidence could change that, and this page explains what it would take.
