This description provides an overview of the age of the Earth, which is estimated to be 4.5 billion years old. This age is based on scientific evidence gathered from various sources, including geological, chemical, and astronomical data. This age is also consistent with the age of the universe, which

The age of Earth is estimated to be 4.54 ± 0.05 billion years. This age corresponds to the final stages of Earth's accretion and planetary differentiation during the early Hadean eon. Estimates are based on radiometric dating of meteoritic material—the ages of which are approached by those of the oldest-known terrestrial material and lunar samples—and accretion models consistent with observations of planet formation in protoplanetary disks.
