BBC Documentary "We Are The Aliens" provides near hour of lively discussion on theory of Panspermia. "The idea that life on Earth came from another planet has been around as a modern scientific theory since the 1960s when it [i.e., Pan- spermia] was proposed by Fred Hoyle and Chandra Wickramasinghe. At the time they were ridiculed for their idea -- known as panspermia. But now, with growing evidence, it's back in vogue and even being studied by NASA. We meet the scientists on a mission to get to the bottom of the beginnings of life on Earth - from the team in Texas who are lovingly building a robotic submarine called DEPTHX to explore a moon of Jupiter, to Southern India where they are investigating a mysterious red rain which fell for two months in 2001. According to local scientist Godfrey Louis, the rain contains biological cells unlike any he had seen before -- with no DNA and the ability to replicate at 300°C. Louis has come to the conclusion that the cells are extra-terrestrial in origin," informs You Tube summary. Red rain in Kerala, India from July to September, 2001 remains one of world's greatest mysteries!
