How were the people that lived in atlantis?

The people of Atlantis, as described by the ancient Greek philosopher Plato, were depicted as a highly advanced civilization with remarkable engineering, architecture, and a rich culture. They were said to be prosperous and powerful, living in a well-organized society that valued wisdom and virtue. However, their hubris and moral decline allegedly led to their downfall, culminating in the mythical island's catastrophic submersion. While Atlantis remains a legend, it symbolizes the idea of a once-great civilization that fell due to its own excesses.
