Some of these samples have been dated to 4.5 billion years old, supporting other calculations of the date of early planetary formation.More than 70 meteorites have fallen to Earth to have their ages calculated by radiometric dating.Scientists attempted to predict the age based on changing sea levels, the time it took for Earth or the sun to cool to present temperatures, and the salinity of the ocean.

Greenland boasts the Isua Supracrustal rocks (3.7 to 3.8 billion years old), while rocks in Swaziland are 3.4 to 3.5 billion years.

The Greek Elysian fields derive from the same celestial topography: the Egyptian "Field of Rushes," the eastern stars at dawn where the soul goes to be purified.

Since the planet Earth doesn't have a birth certificate to record its formation, scientists have spent hundreds of years struggling to determine the age of the planet.

Gravitational interactions coalesced this material into the planets and moons at roughly the same time.

These tiny zirconium silicate crystals have ages that reach 4.3 billion years, making them the oldest materials found on Earth so far. The rocks and zircons set a lower limit on the age of Earth of 4.3 billion years, because the planet itself must be older than anything that lies on its surface.
