In the 1970’s I read about Aliens being the actual architects and builders of Machu Picchu, Ollantaytambo, and other structures in Peru attributed to the Incas. Size and weight of the giant stones in the walls, fitting together perfectly
the open plazas suggesting alien landing strips,
the incredible terracing of the sides of mountains, and the monumental magnitude and scale of the cities, temples, mountaintop storage, and symbolic designs on the ground visible only from the sky were evidence used to “prove” that ordinary humans without modern tools and machines could not have built the structures. They must have been built with the help of extraterrestrials.
The arguments were very intriguing to me and are fun to imagine, but now I have read how the Incas, and Native American civilizations preceding them, built the structures over hundreds of years with skill and industriousness.
Tourists are encouraged not to hand out money, but to buy their wares in order to let them prosper from their own industriousness. From the looks of their handiwork, many of these people are as skilled and hard-working as their forefathers. If the Incas rise again, I wish them peace, prosperity, and a cooperative spirit. The world doesn’t need more nationalistic empire builders, but it does need more educated, healthy, happy people. The friendly people with their incredible history made my visit extraordinary.
