Welcome to Alien Nation – the ongoing series about extra-terrestrials, UFOs, and asks the question “Are we alone?” Hosted by broadcaster Jo Wood, herself an avid believer since seeing strange lights in the sky in Brazil in 1998 (well she’s believed all her life really, but that really sealed it), she talks to other celebrities, experts, and everyday Earthlings who have had close encounters or simply think we cannot be the only planet with life in this vast universe. Listen to their incredible stories every week. Are we alone? Certainly not. Have we been visited by advanced societies? Well how else do you explain the unearthly aerial sightings from around the world? And don’t even get her going on how the Pyramids were built.
