Sars 'from the stars'

http://news.bbc.co.uk/1/hi/sci/tech/2931246.stm

“The virus believed to cause Severe Acute Respiratory Syndrome (Sars) may have come to Earth from outer space, according to scientists writing in a leading British medical journal.”

“Professor Wickramasinghe, who is a leading panspermia enthusiast, says the Sars coronavirus is so unusual that it could not have arisen on Earth.”

My Comments:

Whats the likelyhood of this being a man made virus/biological weapon, created in the chinese labs but was poorly contained and has now spread across the globe?

It would explain why it “appears to be dramatically different from all the other known coronaviruses”
