Although we have been calling Earth our home for many generations, there are many theories that claim humans evolved elsewhere in the galaxy and moved here sometime in the distant past.
Could this controversial and intriguing claim be true? If so, where do we come from and why did our travelling ancestors choose Earth?
Researcher and author Dr. Ellis Silver was best known for proposing a scientific evaluation of evidence suggesting man evolved elsewhere in the universe. In his book, Humans are not from Earth, he lists many reasons for why he believes there is evidence for 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 our human physiology to that of other animals and he believes there are many crucial differences between us. As a species, humans are particularly sensitive to sunlight. The sun has a dazzling effect on humans whilst 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.”
