In numerical terms, the best estimate of Earth’s age so far is that it is close to 4.6 billion years old. But what does that mean exactly? If one uses a human lifetime of 75 years as a measure, the time between Earth’s formation and today has taken more than 61 million human lifetimes!

According to modern biology, the total evolutionary history from the beginning of life to today has taken place since 3.5 to 3.8 billion years ago, the amount of time which passed since the last universal ancestor of all living organisms as shown by geological dating. [24]
Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. [4][5][6] Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen.
