The correct answer is D) All these answers are correct.
The ancient history of the Americas is not as easily understood as that of India and China because we know of the peoples from their artifacts, there were more varieties and numbers of cultures in the Americas, and written records were not kept.
The ancient civilizations of the Americas left some records in rocks and archeologists have interpreted some information through some artifacts they have found in excavations. However, most of those carved in stone representations have not been interpreted because of their difficulty. We are talking about ancient American civilization such as the Toltecs and the Olmecs in southern Mexico. There is such limited information about them that little is known about their lives.
Much more is known about Mesoamerican civilizations such as the Aztecs. But if we refer to the Mayas, most of its messages left in the Mayan stelae have not been interpreted.
