Introduction
Humans have always wondered if they are alone in the universe. The idea of extraterrestrial life is deeply embedded in human culture, and over the centuries our ideas about it have changed greatly. From divine beings in the myths of ancient civilizations to modern notions of "little green men" and intelligent civilizations on distant planets, the history of alien beliefs is a fascinating journey through human history and culture.
Early Myths and Legends
The imagination in ancient civilizations
There have been reports of beings from the sky since ancient times. In Egyptian, Greek and Roman mythology, gods were often depicted as supernatural beings who walked the earth and sometimes descended from the sky. Could these depictions have been an early version of "aliens"? While most of these stories were more religious and spiritual beliefs, they reveal a deep fascination with the unknown and the "other."
Heaven and Gods – Are Aliens Divine?
Many ancient cultures believed that their gods lived in the sky. There are theories that early humans may have interpreted celestial phenomena or extraordinary events as encounters with extraterrestrial beings. This idea of heavenly beings has survived in many religions and cultures to this day.
Medieval ideas
The Influence of Church and Religion
In the Middle Ages, the Christian church shaped people's worldview. The earth was considered the center of the universe, and the idea of extraterrestrial life was not widespread. Instead, people believed in angels and demons, which were supernatural beings but were usually closely linked to religious beliefs. The question of whether there could be intelligent life outside of the earth was not a central issue in Christian Europe for a long time.
The geocentric worldview and the absence of extraterrestrial life
The geocentric worldview, which saw the Earth as the center of the universe, left little room for the idea of life on other planets. Only with the development of modern astronomy did this view begin to change.
Renaissance and the Beginnings of Astronomy
Copernicus, Galileo and the Idea of an Infinite Universe
The work of Nicolaus Copernicus and Galileo Galilei ushered in a new era of astronomy. Suddenly the Earth was no longer the center of the universe, and the possibility that there might be other worlds became conceivable. The Italian philosopher Giordano Bruno in particular went a step further: he claimed that the universe was infinite and that there must be many habitable planets.
Philosophical Reflections on Extraterrestrial Life
This idea led to intense debates in the scientific and philosophical community. Could there be life on other planets? And if so, would that life be intelligent? These were questions that would recur over the next few centuries.

Advances in Astronomy and New Theories
With the advances in astronomy in the 18th and 19th centuries, interest in the possibility of life on other celestial bodies grew. The famous astronomer William Herschel even speculated that the moon could be inhabited. Other planets in our solar system, such as Mars, were also the focus of speculation.
The Emergence of Science Fiction Literature
During this time, science fiction literature also began to flourish. Authors such as Jules Verne and HG Wells wrote about extraterrestrial worlds and beings that humans encountered. These stories shaped the collective image of aliens and formed many people's ideas about the unknown.
The early 20th century – beginning of modern UFO sightings
Roswell and the Emergence of UFO Culture
A major turning point in the modern conception of aliens was the Roswell event in 1947, when reports of a crashed alien spacecraft swept the world. This event sparked a wave of UFO sightings and laid the foundation for modern UFO culture.
Aliens in Pop Culture
Films and series began to take up the topic of aliens more and more frequently. Classics such as "The Day the Earth Stood Still" and "War of the Worlds" helped to establish the image of extraterrestrials as advanced, often threatening civilizations.
Cold War and the Space Race
The fear of alien invasions
During the Cold War, aliens were often used as a metaphor for fear of the "other" and the unknown. The idea of an alien invasion reflected people's fears shaped by the political tensions of the time.
Scientific projects to search for extraterrestrial life
At the same time, scientific interest in the search for extraterrestrial life grew. The SETI (Search for Extraterrestrial Intelligence) project was launched to search for signals from space that could indicate intelligent life.
The late 20th century – emergence of the “Greys” image of aliens
Reports of Abductions and Close Encounters of the Third Kind
In the 1980s, reports of alien abductions became more frequent, often involving so-called "Greys" - small gray beings with large heads and almond-shaped eyes. This depiction became ubiquitous in pop culture and remains one of the most well-known images of aliens to this day.
Aliens as threat or savior?
While some films and books portrayed aliens as a threat (“Independence Day”), other stories described them as friendly beings who wanted to help humanity (“ET”). This dual image of aliens remains a staple of pop culture to this day.
The 21st Century – New Technologies and Theories
Exoplanets and the Search for Habitable Life
Thanks to modern telescopes and space exploration, thousands of exoplanets—planets orbiting other stars—have been discovered in recent decades. Some of these planets are located in habitable zones, which has rekindled hopes of discovering extraterrestrial life.
Scientific discussions about the possibility of extraterrestrial life
The question of whether there is intelligent life outside of Earth remains a central issue in science. The Fermi Paradox, which describes the discrepancy between the high probability of extraterrestrial life and the lack of evidence for it, continues to be debated.
Current developments and visions for the future
Artificial Intelligence and Extraterrestrial Communication
Artificial intelligence is playing an increasingly important role in the search for extraterrestrial life. In the future, AI could help analyze signals from space more efficiently and possibly even decipher alien languages.
New Representations of Aliens in Pop Culture
Even today, the topic of aliens remains present in pop culture. Films and series such as “Arrival” and “Stranger Things” show extraterrestrials in new, often surprising ways and continue to stimulate speculation.
Conclusion
The concept of extraterrestrials has changed dramatically over the centuries. From gods in ancient myths to the tangible aliens of modern pop culture to the scientific projects of today, the search for extraterrestrial life is a journey that has always accompanied the human imagination. Although we do not yet have definitive proof of the existence of extraterrestrials, the question of our place in the universe remains one of humanity's most exciting and important challenges.
