Aliens made the showOne of them has taken the form of Giorgio A. Tsoukalos's hair and controls him like a puppet. The show is meant to sound ridiculous so we can never take any story about aliens seriously. They're lulling us into a false sense of security for their eventual invasion.
The show is secretly sponsored by The Men In BlackGiorgio A. Tsoukalos is either a MIB agent, or an alien they hired to spread information that is slightly true in an attempt to purposely make people think the idea is ridiculous.
This show is in the same canon as Doctor Who.It's just so ridiculous that nobody believes it.
The show is a Stealth Parody of people who believe aliens are real.
