Humans are aliens from outer space: Brit scientist
London: In what sounds to be a new science
fiction theme, a top British scientist has claimed that all
humans are aliens who have come to earth from outer space.
Prof Chandra Wickramasinghe, an Asian-origin
astrobiologist at Cardiff University, said his research
"overwhelmingly supported" the view that human life started
from outside the planet.
According to Wickramasinghe, the first "seeds of life"
were deposited on earth from space some 3,800 million years
He claimed that "microbes from outer space arrived on
earth from comets, which then multiplied and seeded" to form
human life, the Telegraph reported.
"Yes, we are all aliens? We share a cosmic ancestry,"
"Each time a new planetary system forms a few surviving
microbes find their way into comets. These then multiply and
seed other planets.
"We are thus part of a connected chain that extends over
a large volume of the cosmos. Evidence is pointing inexorably
in this direction."
Wickramasinghe said his research, published in the
Cambridge University`s International Journal of Astrobiology,
showed that life is transferred from planet to planet over
billions of years.
According to his theory, all life on earth is brought by
comets hitting the planet. He believes comets hit planets and
pushed living matter out into space.
Some survived and got transferred to new planets over a
timescale of millions and millions of years, he said.
However, the professor -- who alongwith his late
colleague Sir Fred Hoyle championed the so-called "panspermia"
theory from the 1960s -- admits that his theory doesn`t
explain how life actually began in the first place.
"Evidence from astronomy overwhelmingly supports the
view that life did not start on earth but was seeded from
outside," Wickramasinghe said.
"Although we have no definite knowledge how life started
in the first place, once started its spread in the cosmos and
survival is inevitable.
"As we enter a new decade the year 2010 a clear
pronouncement of our likely alien ancestry and of the
existence of extraterrestrial life on a cosmic scale."
