Could the story of Atlantis really be much older than Plato believed?

What if the continents today and the ancient ruins on them above and below sea level, the megaliths and the monoliths and their similar construction methods dating back to the accepted beginnings of human history - are the remains of Atlantean world. What if there was an ancient technologically advanced global civilization..?

Pangea is the first point in time where there could have been a shared architecture, language, history, science, mythology and technology on a global scale.. Pangea existed as a supercontinent for 160 million years, from its assembly around 335 Ma (Early Carboniferous) to its breakup 175 Ma (Middle Jurassic).

Plato lived long before the concept of continental drift was developed. Plato's writings, particularly in the Timaeus, suggest a view of the Earth as a created, living being, a kind of cosmic organism, formed by the Demiurge following an eternal pattern.

Can the timeline of human migration be wrong, really wrong?

If Atlantis had been a city-state on Pangea, it would have had direct land access to every continent, making global trade, shared architecture, and cultural exchange much more plausible. Instead of sinking overnight, as Plato described, Atlantis could have been lost over millions of years due to continental drift, breaking apart as Pangea fragmented.

If we overlay today’s international borders onto the supercontinent of Pangea, the result is a map that drastically changes the relationships and proximities between countries and ancient sites around the world. Mauritania/Richat Structure would have been part of the supercontinents western edge, near what is now the eastern coast of South America. Early human migrations out of Africa (and the possible location of Atlantis) were complex and involved multiple waves of migration over a very, very long period of time.

The timeline of human migration can be significantly more complex and potentially "wrong" in certain aspects than the traditional narratives suggest. While the general idea of humans migrating out of Africa and spreading across the globe is well-established, specific details like the timing, routes, and extent of different migrations are constantly being revised as new evidence, particularly from genetics and archaeology, emerges.

How might a pre-human been able to evolve in the higher temperatures and oxygen levels of 400 million years ago?

Pangea stretched across both the northern and southern polar regions, and its geography and climate created distinct habitable zones.

During the Devonian period, Earth's climate was generally warm, with higher global temperatures compared to today. Pangea had not yet fully formed, but the supercontinent was beginning to take shape. The elevated temperatures were largely influenced by high atmospheric carbon dioxide levels, which contributed to a greenhouse effect.

During this time, vast inland seas covered parts of the land, and tropical conditions prevailed in many regions. The warm climate supported extensive forests of early vascular plants, including ferns and primitive trees. However, fluctuations in temperature and CO₂ levels also played a role in mass extinctions and evolutionary shifts.

Around 350 million years ago, oxygen made up about 20% of the atmosphere, similar to today, and it continued to rise to as much as 35% over the next 50 million years. Oxygen levels began to fall around 300 million years ago, after reaching a peak during the Carboniferous period. This decline is linked to changes in global climate and ecosystems, particularly the death of land plants and cooling temperatures.

Could India's legends of the blue people or blue gods be the last records of the descendants of Atlantis and it's history..?

Methemoglobinemia could have been an adaptation that allowed the Atlanteans to survive in the higher levels of oxygen.

Methemoglobinemia (MetHb) today is a very rare blood disorder, sometimes called “blue baby syndrome,” which affects how red blood cells deliver oxygen to cells and tissues. Not everyone has symptoms, but nearly all people with this condition have skin, nails or lips that are a distinctive shade of blue or purple. It occurs when there is a problem with an enzyme called cytochrome b5 reductase.

Methemoglobinemia is a condition with life-threatening potential for people today in which diminution of the oxygen-carrying capacity of circulating hemoglobin occurs. There are two types of inherited MetHb: Type 1 (also called erythrocyte reductase deficiency) occurs when RBCs lack the enzyme. Type 2 (also called generalized reductase deficiency) occurs when the enzyme doesn't work in the body.

Genetic methemoglobinemia is a rare, inherited condition that affects the function of red blood cells. It occurs when there's a problem with the enzyme cytochrome b5 reductase, which alters hemoglobin in red blood cells. Hemoglobin is a molecule that carries oxygen to the body's tissues, but in people with methemoglobinemia, some normal hemoglobin is replaced by methemoglobin, which can't deliver oxygen.

Summary:

Atlantis was not merely a lost island but a city-state on Pangea, existing during Earth's supercontinent era. Rather than sinking overnight as Plato described, Atlantis could have disappeared over millions of years due to continental drift, breaking apart as Pangea fragmented.

This would mean that Atlantis—or an ancient advanced civilization—had global access, fostering shared architecture, language, mythology, and technology across continents. Ancient ruins, megalithic structures, and similar construction methods found worldwide might be remnants of this Atlantean civilization.

You also explore the timeline of human migration, suggesting that traditional narratives might be incomplete or even incorrect. If Atlantis existed in Pangea’s time, it could explain the similarities among ancient myths and engineering techniques across diverse cultures. Furthermore, sites like the Richat Structure in Mauritania, submerged ruins, and lost cities could be remnants of this civilization.

Additionally, you raise the possibility that legends of blue-skinned beings—such as India's blue gods—could be the last surviving records of Atlantean descendants. You speculate that methemoglobinemia, a condition affecting oxygen delivery in the blood, might have been an adaptation for surviving in higher oxygen levels present in ancient times.

This perspective challenges mainstream archaeology and proposes a slow geological disappearance of Atlantis, rather than a sudden cataclysm. It integrates human evolution, migration, mythology, and lost technology into a broader theory of an advanced civilization predating recorded history.

The Revised Silurian Hypothesis: A Hidden Legacy of Intelligence Introduction The Revised Silurian Hypothesis explores the possibility that an intelligent, tool-using primate species evolved hundreds of millions of years ago, long before the currently accepted timeline of human evolution. This civilization may have existed in small numbers, only in select habitable regions, and could have eventually converged in what would become Africa, forming the foundation of a technologically advanced global civilization—one that possibly included Atlantis. If true, this hypothesis would challenge mainstream archaeology and evolutionary science, suggesting that civilization didn’t begin with humans—it predates them entirely. 1. The Origin of Ancient Intelligence Laurasia and Gondwana housed two separate populations of intelligent, genetically similar primates. Over millions of years, shifting climates and landmasses forced their migration. As Pangaea formed (~300 million years ago), these populations merged in Africa, interbreeding and evolving into a more advanced species. This merging may have led to rapid intellectual and technological advancements, accelerating their evolution beyond simple survival. 2. The Rise of a Hidden Civilization Unlike modern human societies, this ancient species may have had: Low population numbers – avoiding large-scale ecological footprints. Different construction methods – biodegradable materials or advanced techniques that did not leave conventional archaeological traces. Advanced knowledge of Earth’s forces – possibly predicting climate shifts, asteroid impacts, and tectonic movements. Rather than leaving behind obvious ruins, they may have created hidden cities, deep underground or beneath oceans, sheltering from planetary changes. 3. Cataclysm and Erasure At some point, this civilization faced mass extinction—either due to: Natural disasters (volcanism, asteroid impacts, ice ages). Tectonic shifts (continents pulling apart, changing landscapes). Self-inflicted collapse (resource depletion, war, or technological risks). Most physical evidence may have been erased, explaining why their existence has remained unknown. However, remnants could still exist—possibly mistaken for unrelated megalithic structures or submerged ruins. 4. The Legacy of Atlantis If Atlantis was part of this civilization, then: Ancient cities might not be independent—they could be connected remnants of a global empire. Pyramids, Stonehenge, Göbekli Tepe, and other monoliths could be fragments of their knowledge, preserved unintentionally. Ancient myths (gods, lost continents, forbidden knowledge) might be distorted records of their true history. Instead of Atlantis sinking in a single cataclysm, it could be that many civilizations arose from its remnants, unknowingly building over forgotten foundations. 5. What This Means for History If this hypothesis holds merit, it suggests: Our historical timeline is incomplete. We may be misinterpreting our oldest ruins. Deep-sea and underground explorations could reveal long-hidden secrets. Could new discoveries rewrite Earth’s past? Or has this civilization left its traces right in front of us, hidden among the forests of accepted history?
