A new analysis of 36-year-old data, resuscitated from printouts, shows that NASA found life on Mars, an international team of mathematicians and scientists have revealed. The analysis was based on studying the mathematically complexity of the results of a life-detection experiment conducted by NASA’s Viking Mars robots in 1976.

The idea is that living systems are more complicated than purely physical ones, a concept that can be represented mathematically.
Further, NASA doesn’t need a human expedition to Mars to nail down the claim, neuropharmacologist and biologist Joseph Miller, with the University of Southern California Keck School of Medicine, told Discovery News.
“The ultimate proof is to take a video of a Martian bacteria. They should send a microscope -- watch the bacteria move,” Miller said.
“On the basis of what we’ve done so far, I’d say I’m 99 percent sure there’s life there,” he added.
Researchers crunched raw data collected during runs of the Labeled Release experiment, which looked for signs of microbial metabolism in soil samples scooped up and processed by the two Viking landers.
