Probing the esoteric world where it is often necessary to suspend disbelief, consider for a moment that there is evidence of technologies that existed in the very distant past which we no longer have information about today. Visiting Peru and Cusco, the heart center of the former Sun Empire, there are walls and buildings where enormous blocks, presumably weighing many tons, are perfectly set with one another, stacked in perfect harmony. This building happened well before the invasion of the conquistadors in the 1500s. The are other examples such as the great pyramids of Egypt where the building of such domiciles was rather extraordinary. The question is how did these things come into existence and were there technologies in existence then that are not known today?
