The incredible depth of ancient Latin America is fascinating.
Hearkening back to the Olmecs and Toltecs is jaw-droppingly amazing.
Been studying them for years and I agree. Even more amazing (and virtually un-studied and un-researched, probably due to political embroilments and lack of funds) is how the advanced Olmec civilization simply seemed to appear out of nowhere. There has to be a very interesting back-story but so far it's so tangled and incomplete one is merely tantalized.
It reminds me of the Etruscans in Italy who introduced sophisticated metal refining, awesome artistic skills, civil engineering and an advanced, well-organized society seemingly out of the blue. There is sooooo much we still don't know and perhaps never will.
