Mayan times, experience how they built all of their remarkable buildings
and how they developed the extremely accurate Mayan calendar
etc.
or any other time that include building of 7 wonders of the world.
I would love to know how they built the pyramids without tools that we have today...
Was it due to the development of greater intellectual capacity or a product of superstition and unexplained occurrences?
