Why did Magellan give an area of Argentina the name Patagonia?

Ferdinand Magellan named the region "Patagonia" during his expedition in the early 16th century, deriving the name from the Spanish Word "patagón," which he used to describe the indigenous people he encountered there. He believed they were of giant stature, partly due to their large footprints, which led him to think of them as "patagones" or "giants." The name eventually came to represent the entire region known today as Patagonia, known for its vast landscapes and diverse ecosystems.
