This is an episode from Mystery Hunters, an old show that used to air on Discovery Kids and which was also one of the things that got me interested in cryptozoology and unexplained things in general. This episode is "Alien Encounter, Crop Circles". Christina goes to Brazil to investigate an alien sighting, Araya goes to England to find out the truth about crop circles, and Doubting Dave does some crazy science experiments like always. : )
