I’ve been there, it’s life changing experience, such an ominous feeling overwhelmed me in that plaza. You can feel the spirits of the dead in the air. I couldn’t believe the people built such things without the wheel, iron tools, aligned with the heavens. I got home and read every book on the subject, several times, and finally had to move on from it. Too many thing don’t fit.
Look up the Brazilian gold mountain. Theres a photo online that resembles the building of the pyramids. Almost like a glimpse of the past. Humans strength has always been in numbers, for what is weaker than the feeble strength of one?
