Modern scientific thinking concludes that life is a result of an evolutionary process in the universe. Sources of energy acting on the primitive atmosphere are believed to have produced nucleic acids and proteins which are the bases of all life on earth. Analysis of meteorites and the interstellar medium has revealed an array of organic molecules. Chemical evolution which could have led to life on earth may therefore be described as a universal process. The search for extraterrestrial intelligence has become part of the scientific endeavor.
