It's important to note that:
* Atlantis is a fictional city: The story of Atlantis was first told by the ancient Greek philosopher Plato in his dialogues *Timaeus* and *Critias*. He presented it as a legend, not a factual account.
* Plato was a philosopher: Plato (c. 428-348 BC) was a renowned Greek philosopher, not someone who claimed to be from Atlantis. He used the story of Atlantis to explore philosophical themes like justice, morality, and political ideals.
While there are people who believe in the existence of Atlantis, the vast majority of historians and scientists consider it a fictional place.
