About aliens

Since childhood, I have been drawn to aliens, UFOs, and the paranormal. These subjects belong to the realm of fiction, yet they evoke a strangely familiar sensation. Sometimes they feel terrifying, other times intriguing. When people talk about seeing ghosts, I wonder—are they truly glimpsing the spirits of the dead, or are they witnessing something else entirely, something beyond our understanding? Perhaps even ghosts could be a form of extraterrestrial life.

The discussion of extraterrestrial existence has long been a subject of science, philosophy, and popular culture. We search for exoplanets through telescopes, analyze signals, and attempt to determine whether we are alone in the universe. Yet, despite all these efforts, we have not seen them— or perhaps we have, but we lack the means to recognize them.

The idea of extraterrestrial life stirs both fear and curiosity. If they possess a civilization far more advanced than ours, how should we react? Conversely, if they are mere microorganisms, do they still qualify as alien life? More importantly, how much can we truly perceive about the world beyond what is immediately visible?

Carl Sagan believed that extraterrestrial civilizations, if they exist, are likely to be peaceful, and that we should reach out to them. Stephen Hawking, on the other hand, warned that seeking contact with alien civilizations might place us in danger. But beyond the question of extraterrestrial existence, this debate fundamentally reflects how we perceive "the other."

Throughout history, humanity has experienced both fear and fascination toward the unknown. The explorers who first discovered new lands, the sailors who ventured beyond familiar shores, and the astronauts reaching into space all confronted the same dual emotions. This reaction extends to the supernatural—the things we do not understand.

People who claim to have seen ghosts or had inexplicable experiences may simply be victims of illusions or hallucinations. But perhaps these encounters mirror our fascination with aliens—an attempt by our senses to grasp something beyond our comprehension, something that exists on a different plane of reality.
