Quote:
The Hadean period began 4.5 billion years ago, when Earth was just 40 million or so years old. Scientists have long presumed it was a time of hell-like conditions, characterized by scorching temperatures and molten rock.

But the zircons reveal a different story. Chemical signatures embedded in the crystals suggest the planet had water, continents and even interconnected oceans.

This month, researchers studying these zircons made an even more unexpected discovery: the first evidence that life may have existed 4.1 billion years ago. That's 300 million years earlier than was previously thought.
