still blows my mind that there is debate about the origin of Water on earth and much of it is still attributed to the formation of the solar system and as much as 30% to 50% of the water we drink is older than the sun (4.6B years old)

> To be clear, so far some of the oldest ice found is over 6 million years old...

And they're working on finding even older!

"Given the spectacularly old ice we have discovered at Allan Hills, we also have designed a comprehensive longer-term new study of this region to try to extend the records even further in time, which we hope to conduct between 2026 and 2031"
