Massive Evidence of Ancient Alien Culture on Earth Exists in Central & South America: Videos

Tremendous discoveries regarding visitation to earth by alien off world species in prehistoric times have come to light in the past 50 years, and new discoveries continue to take place in the 21st century, astounding those who learn of these amazing inexplicable artifacts. But for the most part, with the exception of programs like “Ancient Aliens” on The History Channel, along with Coast Radio, you won’t hear much news about these history changing discoveries on most mainstream news outlets.

Is there a modern day cover-up on reporting these discoveries? Or is the MSM just attempting to ignore the news to death, in the hopes that by NOT recognizing the obvious, academics and scientists might not be eventually forced to literally re-write the history books about the story of the human species on planet earth?
