A diagrammatic representation of the Earth in the Archaean showing subducted ocean floor carrying its chemical signature into the deep mantle. The signature which includes water and chlorine is preserved in melt inclusions contained within olivine and carried back up to surface within komatiite lava flows.

Does this mean municipalities were chlorinating water supplies 3.3 billion years ago? /sarc

Lol.. 600 million years? Man, that’s better than a comic strip.
HBiased opinions masquerading as science ping. Def not science. Next up the hymalayas will melt by 2035.. o wait.

Isn’t ALL seawater ultimately ancient, though?

I have a feeling that these people have no idea what actual proof of something is.

If you add up all the uncertainties underlying claims of events said to happen hundreds of millions of years ago or more, they add up to north of 99%.

You can’t hand-wave accumulated uncertainty and declare the outcome to be a proof, not if you want to be taken seriously by serious people.
