Who gave these amateurs the authority to declare the petroglyphs as Mayan? Who's to say they really are the earliest? Like, where the fuck are people getting this information from just looking at the thing? The only way I'm going to believe that this is authentically Mayan is if some Maya elder speaks about it or is added to authenticmaya(.com) or Wiki.

P.S. The Mayan Long Count doesn't speak of the world ending, either. Dumb asses. Do some reading.
