20 de oct. de 2013 · For centuries scholars sought to determine Earth’s age, but the answer had to wait for careful geologic observation, isotopic analyses of the elements and an understanding of radioactive decay.
The age of Earth is estimated to be 4.54 ± 0.05 billion years (4.54 × 10 9 years ± 1%). This age may represent the age of Earth's accretion, or core formation, or of the material from which Earth formed.
Based on the very old zircon rock from Australia we know that the Earth is at least 4.374 billion years old. But it could certainly be older.

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!
