The timeline for the history of the planet is based on radiometric dating. Radiometric dating uses the decay rate of radioactive isotopes to determine the age of a sample. The following list includes geological evidence for the age of the earth and life.
|Meteorites||4.6 billion years|
|Zircon crystals in sedimentary rock||4.2 billion years|
|Moon rocks||4.5 billion years|
|Oldest rocks on earth||3.9 billion years|
|Earliest microfossils||3.5 billion years|
