Not one shred of evidence
Let me preface with the fact that I am an avid lover of history.
This nonsense-documentary is embarassing for all those associated with it. It both disappoints and saddens me that this type of rubbish is par for the course for the History Channel. What was once a channel full of relevant and interesting historical content, is now a disgraceful provider of horrible reality shows (Chasing Mummies, Ice Road Truckers, Swamp People, Pawn Stars, American Pickers, Top Shot, etc......) and nonsense documentaries and programming (Ancient Aliens, The Bible Code, Stan Lees' Superhumans, the 976 different documentaries they play linking the Templers, Da Vinci Code and Masons to Jesus's alleged decendents).
Not only does the rock formation NOT look at all to be worked by man, but the argument that it is the most logical place to view these much-anticipated celestial events is ludicrous. Literally, there must be hundreds of thousands of better places to watch these events. But, the Mayan chose a desolate island thousands of miles outside of their known range because the view was good there? HUH?
I say this with sincerity...... "History Channel" should face a court for false advertisement. A channel names "History Channel" must retain a modicum of SOMETHING that is factually historic..... SOMETHING that isn't two guys "picking" their way through Amish country in their little truck...... SOMETHING that isn't a psychopathic Egyptian making little girls cry in the Great Pyramid.... well, actually that last one was pretty funny..... but I digress. Perhaps the History Channel should change their name and allow a more suitable agency take up the mantle of a channel devoted to history.
OK, end of rant.
