The idea that life on Earth came from another planet has been around as a modern scientific theory since the 1960s when it 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. Perhaps Heaven is a planet... The World may never know!
