Are there other human civilizations somewhere else in the universe? New discoveries have revealed to astronomers that humans may not have only evolved on Earth. Astronomers say that the chance that a human civilization evolved only on Earth and nowhere else in the universe is less than about one in a billion trillion (Shekhtman). The universe is so vast that it is possible there are other Earth-like planets capable of supporting life.
The chances that life only evolved on Earth is really low. In fact, Astronomers say that the chance that a human civilization evolved only on Earth and nowhere else in the universe is less than about one in a billion trillion. In the Milky Way, the chance of humans being the only civilization ever to exist increases …show more content…
Nearly all of them have two eyes, a nose, a mouth, two ears, a head, a neck, shoulders, arms, hands, fingers, a torso, two legs, two feet - and they can walk. From an anatomical view, they are practically indistinguishable from humans, yet they are supposed to have come from another planet. According to Neil DeGrasse Tyson, if anything is certain, it is that life elsewhere in the universe, intelligent or otherwise, will look at least as exotic as some of Earth's own life forms (Tyson). According to David Aguilar, Scientists should drop Hollywood's view of humanoid extraterrestrials. In reality, scientists may find some bizarre adaptations (Gambino). When astronomers discover life in the universe, it would not be surprising if they do not look identical to ones from the Hollywood universe.
In conclusion, humans have so much more to discover about the universe, so it is possible that there are habitable planets that can support life. The likelihood that life only evolved on Earth is really small, and astronomers discover new planets on a nearly daily basis. Lastly, when humans discover life, the organisms may not be similar ones depicted by Hollywood films. Next time the sun sets, ponder the question: "Are we alone in the
