why is it hard to find the age of the earth

Answer 1

It is difficult to determine the exact age of the Earth because the planet is constantly changing and evolving. The Earth has been subjected to countless geological processes such as erosion, volcanic activity, and tectonic plate movements which can destroy or alter evidence of its age. Additionally, the oldest rocks on Earth have been subjected to intense heat and pressure over billions of years, making it difficult to accurately date them. Scientists use a variety of techniques, such as radiometric dating of rocks and fossils, to estimate the age of the Earth, but these methods can also be subject to uncertainty and error.
