We don't even need to focus on the big pyramids. Behold these odd artifacts, some found in Ecuador, Los Tayos cave, a place visited by former NASA astronaut:

These stones shine at night when lit with UV light, nobody is sure why or how come and is interesting the Freemason pyramid with the illuminated eye and the steps....

You'll find even stone helmets in such place! Things and instructions were given sometimes. Now, libraries were burned to ashes and who are the ones who kept that lost knowledge? Did they burn the original ones or the copies? Did they memorized some information? The elite has been digesting the leftovers of that, some here, other pieces like these artifacts in South América and each of such group maybe think they have all pieces together. They know more than the rest and, yet, no one has all pieces unless is too powerful and checked it.... like these images above.
