Atlantis

Why the fascination with Atlantis?

We have one source for Atlantis. Plato, who heard of Atlantis from a friend who heard of Atlantis from his grandfather who heard it from solon who heard it from an Egyptian priest. That's the only legitimate source for Atlantis. The story says that Atlantis was at war with Athens. Why isn't that more noteworthy?! Athens is comparable to Atlantis in Platos story and no one talks about that. How much time, effort and money spent to find a mythical city when we could be trying to determine how old Athens actually is. Or we could look into ancient pre deluvian wonders we do know about like Dwarka, Yonoguni, or any number of sites verifiable to 10,000 BC. Atlantis is seriously overrated, if it existed at all.
