Determining the age of the Earth is difficult because most of the original rocks from Earth's formation have been destroyed or altered over time. Additionally, Earth is constantly evolving through processes like erosion, volcanic activity, and tectonic plate movements, making it difficult to accurately date the planet's age. Scientists use a variety of dating methods, such as radiometric dating of rocks and meteorites, to estimate the Earth's age, but there is still some uncertainty and debate among researchers about the exact age of our planet.
