there is a huge conspiracy to manipulate the result of every discovery of archeology ... for example in Palenque we have the tomb of an ancient astronaut... legends and even the engravement of the tomb tell a story of a guy piloting a flying machine... but officially is just some priest or king in his throne...

why they keep ignoring the similarities between the sites of the Mayan, the Inca and the Sumerians and Egypt?

Right now in Mexico city we have an exposition of ISIS and the feather Serpent...
Why they mention a flying Serpent everywhere?
