However, the scientists believe they have found the first proof of alien life after harvesting strange particles from the edge of the Earth’s atmosphere.
It is of particular attention that a team from Sheffield University collected organisms from high in the stratosphere which, they claim, are too large to have originated on this planet.
While, Professor Milton Wainwright, who led the project, said the results could be revolutionary, and “completely change our view of biology and evolution”.
On Thursday Prof Wainwright told The Scotsman: “These are some very unusual species indeed. We have been carrying out this research for the past 12 years but we haven’t seen anything like this until now.
“Before, we found bacteria which is interesting to us but not to the public at large. So when these first came up on the computer, it was unbelievable.We are talking about complex organisms with, for example, a proboscis, two nostril-like openings, and what is in effect a sphincter.”[ scotsman.com ]
