We are all ETs: scientists revive theory that life didn’t originate on earth
23 Apr 2018
A bunch of scientists has given a fresh lease of life to the Panspermia hypothesis, which claims that life did not originate on earth but was propagated by bacteria distributed in space dust, asteroids or meteors that arrived on earth.
Scientists were recently stunned to find two ancient meteorites which crash landed 20 years ago containing the basic building blocks for life.
According to experts, life spreads like an "interstellar infection" and clusters of planets in the galaxy have alien life forms.
US-based ecologist Dr Ellis Silver points to a number of physiological features to make his case for why humans did not evolve alongside other life on Earth, in his new book.
They range from humans suffering from bad backs, which he suggests is because we evolved in a world with lower gravity, to getting too easily sunburned and having difficulty giving birth.
Dr Ellis says that while the planet meets humans' needs for the most part, it does not perhaps serve the species' interests as well as the aliens who dropped us off imagined.
In his book, Humans are not from earth: A scientific evaluation of the evidence, the ecologist writes the human race has defects that mark it of being "not of this world".
"Mankind is supposedly the most highly developed species on the planet, yet is surprisingly unsuited and ill-equipped for Earth's environment: harmed by sunlight, a strong dislike for naturally occurring foods, ridiculously high rates of chronic disease, and more," he told Yahoo.
Dr Ellis also says that it is strange that babies' heads are so large and make it difficult for women to give birth, which can result in fatalities of the mother and infant.
Silver wrote in the Daily Star he would be surprised if one could find a single person who is 100-per cent healthy and not suffering from some perhaps hidden or unstated condition or disorder.
He suggests that Neanderthals such as homo erectus were crossbred with another species, perhaps from Alpha Centauri, which is the closest star system to our solar system, some 4.37 light years away from the sun.
Bizarrely, he also believes earth could actually be some kind of galactic jail.
"The earth might be a prison planet, since we seem to be a naturally violent species and we're here until we learn to behave ourselves," he said.
The theory that life started elsewhere has gained credence recently, albeit without the aliens.
Two space rocks, which are approximately 4.5 billion years old, smashed into Texas and Morocco in 1998. Studies have found that both the meteorites, which are thought to have originated from an asteroid belt between Jupiter and Mars, contained water and organic compounds.
While other scientists have said some bacteria arrived on Earth from space, Chris McKay, an astrobiologist at NASA, said that to jump to the conclusion that it is alien life is "a big jump".
Professor Wainwright from the University of Sheffield in the UK plans to investigate further, and believes that life is constantly arriving from space that did not originate on earth.
