In early August, the scientists of NASA/Goddard Space Flight Center made an official statement revealing the discovery of building blocks of alien DNA found in meteorites and admitted that life on Earth has an extraterrestrial origin. NASA is saying nothing different from the "Cosmic Panspermia" theory, created in the 18th century and largely mentioned by the supporters of the "Ancient Astronaut" theory.
Though, NASA scientists have limited the discussion to nucleobase compounds.
