I want to know the answer to the following question:
What term is used most often when discussing the great civilizations of the Americas?
All the background I'm provided with is that "While technically referring to the era before Christopher Columbus' voyages of 1492 to 1504, in practice the term usually includes the history of American indigenous cultures until Europeans either conquered or significantly influenced them, even if this happened decades or even centuries after Columbus' initial landing.". Is that enough to answer the question?
Answer: no
