A piece of zircon found on a sheep ranch in western Australia has been dated as some 4.4 billion years old - almost as old as the 4.5 billion-year-old planet itself.
The tiny crystal was subjected to Uranium-Lead dating to determine its age. Then, to avoid the risk of a misleading date, the findings were confirmed via a seperate, independent dating method "known as atom-probe tomography that was able to identify individual atoms of lead in the crystal and determine their mass, and confirmed that the zircon was indeed 4.4 billion years old.

At the age of five, Skagra decided emphatically that God did not exist. This revelation tends to make most people in the universe who have it react in one of two ways - with relief or with despair. Only Skagra responded to it by thinking, 'Wait a second. That means there's a situation vacant.'
