How much of human history is lost?

Human history is a vast tapestry of triumphs and tragedies, innovations and civilizations that have shaped the world as we know it today. It is an invaluable resource that helps us understand our roots, learn from our past mistakes, and gain insights into the complexities of human society. However, it is a sobering fact that a substantial portion of human history has been lost to the ravages of time. In just the span of a few hundred thousand years, Earth has seen the disappearance of 2.5 billion years’ worth of evolutionary history. The magnitude of this loss is truly staggering, prompting us to delve into the concept of lost human history and explore the factors that have contributed to its demise.

The concept of lost human history

To comprehend the concept of lost human history, it is essential to define and understand its scope. Lost human history refers to the knowledge, discoveries, and achievements of past civilizations that have been irretrievably erased or remain unknown to us today. It encompasses the collective wisdom of ancient cultures, their technological advancements, societal structures, and artistic expressions. The loss of human history is not limited solely to ancient times but includes more recent periods as well.

There are various factors that have contributed to the loss of human history. Natural disasters such as fires, floods, earthquakes, and volcanic eruptions have destroyed countless historical records and artifacts over the millennia. Additionally, human actions, including wars, conflicts, iconoclasm, and religious persecution, have intentionally wiped out significant pieces of history.

Ancient civilizations and lost knowledge

The disappearance of ancient civilizations brings with it a profound loss of knowledge and understanding. One prominent example often debated is the legend of Atlantis, a mythical civilization said to have sunk into the depths of the ocean. While its existence remains unproven, the idea of a technologically advanced society vanishing without a trace captures the imagination. Similarly, the Mayan civilization, renowned for its impressive architecture, sophisticated calendar system, and advanced knowledge of astronomy, experienced a decline that resulted in the loss of much of their cultural and scientific achievements. Ancient Mesopotamia, often considered the cradle of civilization, produced remarkable advancements in writing, law, and architecture. Yet, much of its knowledge has been lost due to centuries of conflict and the passage of time.

The destruction of historical records

The destruction of historical records has been a significant contributor to the loss of human history. Natural disasters have played a role in erasing traces of the past. Devastating fires, such as the burning of the Library of Alexandria in ancient Egypt and the destruction of the Imperial Library of Constantinople, resulted in the loss of countless volumes of knowledge. Similarly, floods have swept away ancient texts and documents, while earthquakes have crumbled structures that held valuable historical information.

Human actions have also played a role in intentionally erasing history. Wars and conflicts throughout history have led to the deliberate destruction of cultural sites, libraries, and artifacts. The conquest of the Aztec and Inca civilizations by European colonizers resulted in the loss of invaluable indigenous knowledge and cultural artifacts. Iconoclasm, the intentional destruction of religious symbols and artworks, has erased entire chapters of history. The Taliban’s destruction of the Buddhas of Bamiyan in Afghanistan and the iconoclasm carried out during the Protestant Reformation are prime examples.

Loss of indigenous cultures and oral histories

In addition to the loss of ancient civilizations, the disappearance of indigenous cultures and their oral histories represents a significant loss of human history. Indigenous cultures around the world possess unique knowledge systems that have been passed down through generations. They hold wisdom about sustainable practices, medicinal plants, and spiritual beliefs that are intricately woven into their cultural fabric. However, colonization, forced assimilation, and language loss have led to the erosion of these vibrant cultures. With the decline of indigenous languages, centuries of knowledge encoded in oral traditions are rapidly disappearing, jeopardizing our understanding of their rich histories.

Historical revisionism and censorship

In some instances, the loss of human history is not solely due to natural disasters or the passage of time but is a result of intentional revisionism and censorship. Throughout history, various governments and regimes have manipulated and distorted historical narratives to suit their agendas. Nazi Germany under Adolf Hitler rewrote history to promote Aryan superiority and justify their atrocities during World War II. Similarly, the Soviet Union suppressed historical facts and promoted state-sanctioned narratives to control the masses and maintain their grip on power.

Recovering lost history

Efforts to reconstruct and recover lost historical knowledge are crucial in preserving our collective human heritage. Archaeological discoveries continue to unearth buried civilizations and shed light on previously unknown aspects of history. The meticulous preservation and restoration of artifacts and historical sites ensure that future generations can learn from and appreciate their significance. Moreover, the advent of digital archives and data storage has revolutionized the preservation of historical records, making valuable information accessible to a wider audience and guarding against potential loss.


The extent of lost human history is a stark reminder of the fragility of our past. The disappearance of ancient civilizations, destruction of historical records, loss of indigenous cultures, and intentional revisionism all contribute to the overwhelming magnitude of this loss. As custodians of our shared history, it is our duty to continue studying, preserving, and recovering as much of it as possible. By doing so, we can honor the knowledge and achievements of our ancestors and ensure that their legacies are not forgotten.
