Ancient Aliens step-cousin
Basically, both shows follow the same confirmation bias. Here's a theory/story/event. Show says it's Aliens or paranormal and the speakers agree with the title.
If it's some random. Guy in trees caught on tape, it's a ghost. If a fan is blowing a blanket and no one in the video reacts, it must be a ghost. If a structure was built and we don't know how it was built, it must be aliens.
Both are fun to laugh at.
