Japan-based researchers have found carbon fragments in 3.95-billion-year-old rocks in Canada, claiming it to be the oldest-known life evidence on Earth. The team said it found same carbon isotope ratios seen in living organisms. The find is being scrutinised as some scientists believe, until 3.8 billion years ago, several space bodies crashed into Earth, making it difficult to create life.
