The Earth crust is continually being created, modified, and destroyed. There is substantial evidence that the Earth and the other bodies of the Solar System are 4.5-4.6 billion years old, and that the Milky Way Galaxy and the Universe are older still. There was no atmosphere on early earth. Thus, the correct answer is option A.
