Although we have been calling Earth our home for many generations, there are theories that claim humans evolved elsewhere in the galaxy and moved here sometime in the past.
Could this controversial and intriguing claim be true? If so, where do we come from and why did our travelling ancestors chose Earth?
Researcher and author Dr. Ellis Silver proposed a scientific evaluation of the evidence that suggests man evolved somewhere else in the universe. In his book, Humans are not from Earth, he lists several reasons which he believes places mankind’s ancestry outside of the blue planet. He also evaluates possible points of origin and a timeline for our appearance on Earth.
Dr. Silver compared human physiology to that of other animals and he believes there are some crucial differences between them. As a species, humans are particularly sensitive to sunlight. The sun has a dazzling effect on humans while most animals seem immune to this effect. While reptiles use heat from the sun to regulate their own internal temperature, humans experience serious troubles if exposed for more than two weeks. According to Silver, this behavior constitutes evidence that humans might have evolved on a planet with considerably less sunlight. Our genetic make-up was able to adapt to this increased radiation but not without cost.
Humans also suffer from chronic illnesses at a much higher rate than other animals. This could be the result of a struggle to cope with damaging factors that weren’t present at the time of our evolution. “We are all chronically ill,” says Silver. “Indeed, if you can find a single person who is 100% fit and healthy and not suffering from some (perhaps hidden or unstated) condition or disorder I would be extremely surprised – I have not been able to find anyone.”
People suffer from bad backs and have done so throughout our history. Dr. Silver believes this problem can be traced back to humans evolving on a planet with a much lower gravity. Despite being the most advanced species on Earth, we are surprisingly ill-equipped for life here: sunlight harms us, we are plagued with illness and we have a strong dislike for raw or naturally occurring foods. And then there’s the overwhelming feeling of not belonging here that so many people experience. Dr. Silver claims this is not a passing thing but rather some kind of genetic longing for home.
“The Earth approximately meets our needs as a species, but perhaps not as strongly as whoever brought us here initially thought,” Silver said in an interview with Yahoo news.
Our internal body clocks evolved to work in conjunction with a 25-hour day. Silver believes this missing hour accounts for many of our biological problems and his claims are backed up by sleep researchers. This complication is not something recent and can be traced back through mankind’s history.
Dr. Silver explores the possibility that early pre-humans like Homo erectuswere crossbred with another species. Life on Earth could have arrived on comets or meteorites. The primitive life-forms evolved for billions of years into the species we see today but humans did not.
They evolved from a different strain of life somewhere else in the universe and were brought here as fully evolved Homo sapiens. This happened somewhere between 200,000 and 60,000 years ago. Silver speculates this could have happened for many reasons, the most interesting of them being that Earth might be a prison planet. He believes this could account for our violent nature and behavior. If this is the case, how long are we in for?
The book has been met with a healthy dose of criticism but as Dr. Silver points out, it is just speculative writing aimed at sparking debate. In any case, it makes for an interesting read.
