Bolivia isn’t in Meso-America and neither were the Incas. hint: Meso-America is in North America.
I think you’re a little confused.
Mesoamerica was normally considered to be southern Mexico and down through Central America to the top of South America.
The Incas were considered a Mesoamerican culture and ranged from Colombia at the top of South America, down the west coast to the bottom of Chile.
They were definitely in Bolivia.
Not among the archaeologists I knew (or was taught by).
