In an effort to further refine the age of Earth, scientists began to look outward.

The material that formed the solar system was a cloud of dust and gas that surrounded the young sun.

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.

Samples in Western Australia run 3.4 to 3.6 billion years old.

Several attempts to scientifically date the planet have occurred over the past 400 years.

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.

As science progressed, these methods were proven to be unreliable; for instance, the rise and fall of the ocean was shown to be an ever-changing process rather than a gradually declining one.

In an effort to calculate the age of the planet, scientists turned to the rocks that cover its surface.

The nearest body to Earth, the moon, does not suffer from the resurfacing problems that cover Earth's landscape.
