They definitely exist and they could be living among us on Earth. That’s what Britain’s astronaut Helen Sharman is sure of. “There are so many billions of stars out there in the universe that there must be all sorts of different forms of life. Will they be like you and me, made up of carbon and nitrogen? Maybe not. It’s possible they’re here right now and we simply can’t see them.”
Helen is not the only person to speculate that we’ve had brushes with aliens, though. A former Pentagon official who led a secret government program to research potential UFOs, revealed in 2017, told CNN at the time that he believes there is evidence of alien life reaching Earth. And besides, it is well known that many Americans think the government is hiding knowledge of the existence of extraterrestrial life forms. Over the years, the testimonies of regular close encounters of the third type have multiplied, together with references to some hieroglyphics of past civilizations — Head of the Cairo University Archaeology Department, Dr Ala Shaheen in December 2010 had told an audience that there might be truth to the theory that aliens helped the ancient Egyptians build the oldest of pyramids, the Pyramids of Giza.
The term “alien” is derived from the Latin alienus, meaning stranger, foreign, etym. “belonging — somewhere — else”. Similar terms to “alien” in this context include foreigner and lander. That’s why it covers everything that people associate with isolation, from their environment or from other people. People who show symptoms of alienation will often reject loved ones or society. They may also show feelings of distance and estrangement, including from their own emotions. It’s a complex, yet common condition, both sociological and psychological, and can affect health and aggravate existing medical conditions. It’s almost as if somehow some bodies are unable to adapt to the earthly habitat and its rhythms — as seen in movies like Steven Spielberg’s E.T. the Extra-Terrestrial and War of the Worlds or Jonathan Glazer’s Under the Skin.
So, maybe the only question you might want to ask yourself is: do they come from remote space or they’ve always been here, among us?
