The Mayan Astronaut: The technical interpretation of the Palenque tombstone

The Palenque tombstone from a technical point of view. Without religious rites and without a tree of of life, but a flying cart. Made with the remains of a high civilization? Were the Anunnaki involved? Were the Ancient Astronaus humans from one of our old civilizations ? Or were they visitors from some other planet ? The author is more and more convinced that the so called "visitors" or Gods came from our own solar system and due to the "cooling" of our Sun they moved towards the center of the solar system. Therefore he presume that the Species Homo Sapiens has developed on another planet or moon of our own solar system. Eventually, however, the species Homo Sapiens could have developed on Earth. After a possible great natural catastrophe mankind was reduced to the stone age. The survivors of that time (assuming that this theory is right), were perhaps working in Earth orbit, in large space stations. Who knows? Perhaps, when the Palenque tombstone was chiseled, this flying object had not existed for centuries. Since photos bleach very quickly, these may not have existed anymore. The author assume, however, that technical plans on thick paper still existed and were still in the orbital stations. Unfortunately the Catholic clergy destroyed just about everything they found. Thus the last evidence was also eliminated.
