Hi @delishtreats! I want to thank you for your detailed comment. The llamas are not wild, I would say they are domesticated in South America, so they do not show any sign of fear.
The Inca civilization placed a great importance on astronomy. They were kind of Experts:) They were the only culture in the world to define constellations of both light and darkness. So that is why I was not surprised of what they have built.
Thank you one more time, I wish you to visit Ecuador, have a nice time over there and take pics even better than mine.
