6. Are UFOs a Hoax?
Every once in a while, there appears a photo depicting a UFO and people start panicking and developing all sorts of theories that spread like fire. But despite the fact that most of these strange apparently inexplicable events prove to be hoaxes, a large number of people believe the UFOs are real. There are entire groups of UFO enthusiasts who collect evidence that we have been visited by aliens. This is definitely a fun debate topic for high school students.
