Answer: The sunken city of Atlantis has never been found, and many critics assume that Plato invented the story of Atlantis to warn people what might happen if they continue with their habits.
Explanation:
Atlantis is a lost city which was first mentioned in Plato's dialogues, around 360 B.C.
Many critics assume that Plato created the whole story of Atlantis, to support his philosophical theories. In his work, Plato often included the elements such as utopian societies, corruption, human habits, etc. Therefore, Atlantis could be interpreted as his attempt to warn people of the gods' punishment for their habits. This theory is supported by the fact that there are no records of the existence of Atlantis apart from Plato's dialogues. Moreover, no trace of the sunken city has ever been found by the oceanographers.
