Earth is approximately 4.54 billion years old.

The age of the Earth was determined through radiometric dating of rocks and minerals.

Radiometric dating involves measuring the decay of radioactive isotopes within rocks.

The oldest rocks on Earth, found in Western Greenland, date back to around 3.8 billion years.

The Earth's age is based on evidence from various sources, including lunar samples, meteorites, and Earth's geological formations.

The age of the Earth provides valuable insights into the early history of our solar system.

The formation of Earth occurred as part of the accretion of dust and gas around the young Sun.

Early Earth was a hostile environment with extreme heat and volcanic activity.

Life on Earth is believed to have originated around 3.5 to 3.8 billion years ago, not long after the planet's formation.

Earth's age is central to our understanding of geology, evolution, and the development of life on our planet.
