How the Oldest Rocks on Earth Changed History

The video explores Earth's geological history, focusing on zircon crystals found in Western Australia, which are 4.4 billion years old. These crystals challenge previous beliefs about the Hadean Eon, suggesting a cooler early Earth. The video also discusses older rocks from meteorites and the moon, providing insights into the solar system's formation. These findings highlight the importance of geological samples in understanding Earth's and the solar system's history.

Why are the zircon crystals considered important for the 'cool early Earth hypothesis'?
