The Earth is estimated to be approximately 4.54 billion years old, based on radiometric dating of rocks and meteorites.
Scientists use various methods such as radiometric dating, geological evidence, and astronomical observations to estimate the age of the Earth.
The main controversy surrounding the age of the Earth is between those who believe in a young Earth (less than 10,000 years old) based on religious beliefs, and those who accept the scientific consensus of an ancient Earth.
The evidence for the age of 4.54 billion years includes radiometric dating of rocks and meteorites, the study of Earth's geological processes and history, and the observation and analysis of the universe's expansion and age.
The age of the Earth is constantly being refined and updated as new evidence and technology become available. However, current scientific consensus supports an age of 4.54 billion years and this is unlikely to change significantly in the future.
