Here's some comedy gold: UFO Files: Ancient Aliens
This kind of program is always entertaining even if it is unintentionally so. What amazes about people that believe this stuff is that they're willing to take the miraculous events found in ancient texts possible while at the same time denying the known as real. For example, they'll believe that various Biblical references indicate the presence of aliens while being baffled that someone could build a pyramid. Visitors from space bequeathing civilization are more plausible than Egyptians finding the cardinal directions. Apparently it escapes these people that fiction and fictional embellishments to histories are as old as storytelling.
Another odd facet of these beliefs is the notion that entire disciplines of scientists, in this case archaeologists, are engaged in a massive coverup of facts that would rewrite all of human (pre)history. Believe me, nothing would bring more delight to an archaeologist, or scientists of any stripe, than overturning an existing paradigm and replacing it with something novel. Such a feat would secure anyone's legacy beyond narrow disciplinary definitions.
Silly.
But definitely entertaining.
