Hi Megan,
As Kris says, our ancestors were pretty clever folk and with the help of many of their people (some of whom were slaves), they built some amazing structures. In Peru in the not so distant past (maybe 500 - 600 years ago), the Inca built structures of huge stones. Many people question how the Incas could build with these stones and fit them together so precisely (at Sacsahuaman, for example). All it takes is a good engineer and a lot of workers and the Inca had both! Quarries have been found close to Sacsahuaman, Ollantaytambo, and at Machu Picchu. In some cases in the ancient world, slaves were used to create these buildings. In other cases, the workers were not slaves, but were working for the state, doing their civic duty.
So to answer your question directly, I have seen no evidence of an extraterrestrial connection in Peru.
