The Definition of Alien

Alien life or extraterrestrial life, is life form that possibly exists outside of Earth and does not originate from Earth. Although studies are in progress, no conclusive evidence of extraterrestrial life has yet been found.

However, that does not curb humans’ fascination with the speculation of the existence of alien life forms. In fact, since antiquity, various Christian writers and early thinkers have discussed this idea. In turn, it continues to fuel the general public’s interest in this matter. As a matter of fact, 75% of Americans believe in the presence of extraterrestrial life.

The question, then, is…

Why Do Alien Stories Fascinate Us?

We are fascinated by alien stories due to our curiosity and desire to comprehend that which we cannot explain, in this case, our lack of understanding about the greater universe and what’s potentially out there.

Our fascination with aliens also stems from the fact that we love the comparison between us and ‘them’. Fermilab Don Lincoln opined about it here, and we quote:

When we talk about the more intelligent extraterrestrials, we’re really holding a mirror up to ourselves… If we didn’t see ourselves in the vision, we wouldn’t find them [aliens] nearly as fascinating.
