Alright.. there temple works as a 6 number calender, you can tell the time by looking at how the sun hits it. Everytime the equinox hits it, it creates serpant shadows. You might have trouble comprehending these people much more complex then you, or anyone else. They know shit we don't that should be obvious. "By far the most impressive structure of the complex is the "Pyramid of Kukulcan" * (usually called "El Castillo"). This is a square-based, stepped pyramid approximately 30 meters tall (with the temple on top), constructed by the Mayans ca 1000-1200 AD, directly upon the multiple foundations of previous temples. It was mysteriously abandoned along with the surrounding city of Chichen Itza by 1400 AD."
"The pyramid has special astronomical significance and layout. Each face of the pyramid has a stairway with ninety-one steps, which together with the shared step of the platform at the top, add up to 365, the number of days in a year. These stairways also divide the nine terraces of each side of the pyramid into eighteen segments, representing the eighteen months of the Mayan calendar"
"The pyramid's design reflects the equinoxes and solstices of our solar year in a spectacular game of light and shadow. During the equinoxes, the setting sun casts a shadow of a serpent on the northern steps of the pyramid."
