This is projection due to such medias being the extent of your knowledge as it pertains to ancient Greece.

The Atlantean myth describes a utopian empire that rules over the waves and eventually conspires against the known world before being destroyed by the gods for its hubris. Plato cannot be trusted as a historical source, not the least bit for being the progenitor of the noble lie. If there were no historical events of peoples that match the story, then there would be no reason to interpret it as anything but a story, but as I said previously, it is very clearly based on a real people and the events that surrounded their fall.

The thalassocracy of Minoan was a multi-island hegemonic empire that dominated the Mediterranean through trade during a time we refer to as Pax Minoica, or the middle to late bronze age. Central to this was the elaborate bronze age trade network, or palace economy. The Minoans had advanced hydro-engineering, buildings with the Fibonacci sequence in their proportions, optical lenses, wealth distribution, hot and cold running water, toilets, advanced metalworking, an abundance of food, communitarian infrastructure, a matriarchal society, and elaborate security measures using naval prowess, mountain bases, and obtuse architecture for invading forces.

Everything that Plato describes about the society, from their advanced hydro-engineering and architecture, to their fertile fields near Mount Ida, to even the colours with which they painted their buildings, matches the great grandeur of Knossos. He describes a nation that controls movement on the seas, an island that is a gateway to all other islands and lands of the known world. This is exactly the role they served during the bronze age, a gateway between the Mediterranean, Levant, and Africa, the then-known world. And just as described, this rule over the seas spread to the Gates of Herakles.

In 1600 BCE, the Santorini volcanic eruption devastated Minoa. It took many years before some of the palace sites were rebuilt, but it was not the end of their civilization. What we see instead is a waning of their influence and power, and a growing influence of the power of Mycenean Greece. After hundreds of years of a slowly shifting power balance, along with so many earthquakes that not even their earthquake-resistant structures could withstand, and floods from those earthquakes devastating their trade, the Minoan hegemony totally collapsed. With their people utterly desperate, a popular uprising occurred in 1200 BCE, and after burning their very cities to the ground, the Minoans proceeded to raid Cyprus, the Ugarit, Mycenae, the Levant, Egypt, and more in what is commonly referred to as the Sea People invasion. This is the great conspiracy against the circuit of the world that is described in both Plato's Atlantis, and Ramesses III's description of the events.

Thus, the story of Atlantis is the story of a very real hegemonic and technocratic trading empire that, after a series of cataclysmic events, lost their footing amongst their neighbors, and set out to try and change that with force. What I'm describing is not fantasy, it is not fiction, it is the history of human civilization, and a well-documented one at that. In other comments, you're asking for "lost records" as if there aren't hundreds, if not thousands, of scholarly articles and books on this subject. If only you were as curious about the annals of human history as you are about the history of Star Wars and Star Trek. Let me tell you something that will help you be less terminally uncurious: knowledge outside of your periphery does exist, it does for us all. Making presumptuous statements about subjects we don't really know is pure ego.

Graham Hancock is a great example of that. Whether he realizes it or not, he's taking away from our ability to understand the real thing by drawing attention towards fantasy for frivolous reasons, such as ego. And whether you realize it or not, people like him have informed your view of the subject as well, since you only view it as their fantasy, and thus toss aside history. We didn't need Plato to tell us the story of Minoa, the events described are well recorded all over the bronze age world, during and after. Plato's retelling, exaggerated or not, is simply the most popular iteration and name for them. That's the only reason why Plato's story is valuable, its popularity has the potential to shed light on real people that are currently relatively underserved in archaeology.
