Answer:Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen.
Explanation:
Earth formed from debris orbiting around our sun about 4 ½ billion years ago. That is also the approximate age of the sun, but it is not the beginning of our story. The story really begins with the Big Bang nearly 14 billion years ago, which spewed hydrogen atoms throughout the universe.
