And Other American Pyramids
Although archeologists are dating the Cohokia Mounds at around 1000-1200 AD, the template would have been formed much earlier.
Questions would be, how and why a city housing over 20,000 people would be built and then all the inhabitants just disappear? Of course, if the Norse really did come much earlier than Columbus, maybe they brought some other diseases that caused an epidemic?
Did the Western Hemisphere lose the knowledge of how the Pyramids generated and broadcast power, but remembered how to build the structure and still believed it to be a way of ‘having’ power?
