Looking at the entire metropolis, it becomes obvious that this was a well planned community, developed by a highly evolved civilization. The number of ancient gold mines suggests the reason for the community being in this location. We find roads -- some extending a hundred miles -- that connected the community and terraced agriculture, closely resembling those found in the Inca settlements in Peru.
But one question begs for an answer -- how could this be achieved by humans 200,000 years ago?
