Went to Chichen Itza last year and the pyramid of the serpent god(El Castillo) is a technological marvel.It was built to be in perfect alignment with spring and fall equinoxes thus casting the serpent on the staircases.But that is just the one of the many wonders of this structure. The pyramid is also a giant amplifier of sound.This was supposedly done by design.This was not an accidental creation.It amplifies sound a 1/4 mile around it and sounds at the top of structure.Also it was built in angular alignment with two star systems,just like the Egyptian pyramids.Also this pyramid is built on top of an even older pyramid structure.They are excavating the west side currently.This is the place where they might have found heirolglyphs that might reflect alien contact.It was roped off so people could not access though.This is what is coming out in movie in Aug.2012.These people had technology beyond our own in building and in the knowledge of the cosmos!Their must of been some sort of influence for all this and it very well could be extraterestrial.CANT WAIT FOR THE MOVIE!
