The Aztecs did not build a city on a lake. That city was already there, built some few hundred years before by a group of people who did not leave their names. Some historians and archaeologists suspect that it may have been the Toltecs or the Mixtecs who built the city, and the Aztecs themselves regarded it as the mythical city of Tollan (home of the Toltecs). Current scholarly research still has no definitive answer.
