How are human different than aliens
Answers
Are we alone? Humans have a lot of questions about alien life. But those beings, if they exist, likely have some questions of their own about humans, queries we may want to answer before we find any life beyond Earth.
That's because the answers we reach will shape how we respond to any such discovery in ways that have profound implications for us and that hypothetical life beyond Earth alike, according to Kathryn Denning, an anthropologist at York University in Canada who focuses on space exploration and extraterrestrial life. Some of those questions, the more anthropocentric ones, are already in the air, underlying conversations about the search for life.
Explanation:
Panspermia is a mechanism that allows biology to spread through space without needing a spaceship. Living matter “hitches a ride on sunlight or inside rocks.” Some scientists believe that Mars was indeed inhabited at one time. Some space rocks were “kicked” off the planet and landed in a “suitably welcoming patch” on Earth. Biological material from Mars that was in the rocks may spur exploration into the search for the solution to the age-old question: Where do we come from and why are we here? There are several theories that relate to extraterrestrials.
For example, did aliens escape from an unknown planet and come here due to dire circumstances on their home planets? Are we descendants of this race? Environmentalist and ecologist turned author Dr. Ellis Silver believes this is the case.
In his book, Humans are not from Earth: A Scientific Evaluation of the Evidence, Dr. Silver presents 17 reasons why humans are not suited for living on this planet. He believes these reasons indicate we originated from another planet. He says that while Earth meets some of our needs as a species, it is not as good a fit for us as much as “whoever brought us here initially thought.”
Silver gives some examples of our unsuitability for living on Earth. For example, he states that humans do not do well with large doses of sunlight, which we receive every day. He also notes there are a large number of people in the world who have chronic back aches, which he attributed to evidence that we originated from a planet with lower gravity. He also notes that we are better programmed to exist with a 25-hour day instead of a 24-hour one.
Silver suggests we may have come from Alpha Centauri. The planet may have suffered some type of cataclysmic event from which a few residents were able to escape and come to Earth.
