Ancient Aliens takes bullshit to a whole new level! It is oddly entertaining however, if you can suspend your disbelief.

My favourite in this regard was a series I saw a while back called 'Finding Bigfoot'. Well-meaning but highly deluded loons roam around the woods of the US, howling into the wind int the hope of bumping into a sasquatch. 😁
