Recreating Earth's Ancient Past: Evidence of Early Life and Conditions

Scientists from the US and Australia have reconstructed a picture of Earth 4 billion years ago, suggesting it was cool enough to support water and life, contrary to previous beliefs of a molten surface. Their conclusions are based on the study of zircon crystals, which remain unchanged by extreme conditions. These findings indicate that life may have existed on Earth a billion years earlier than previously thought. The team aims to study zircon crystals globally to better understand early Earth conditions.
