In April 1997 39 devotees to a UFO cult called Heaven’s Gate cult led by Marshall Applewhite, killed themselves believing after their deaths they would join an alien space they said was riding piggy-back on a comet. This event brought to the forefront again just how many people actually believe in UFOs and aliens. Although Heaven’s Gate represents the radical fringe of a global UFO movement, there are millions of less-dedicated, everyday followers who believe in UFOs and alien life.
