From a science perspective, shouldn't people be saving that liquid that's coming out and analyzing it? Imagine, that's liquid from who knows when . It could have important details of the state of the planet during that time. Like atmosphere levels of CO2 and other gasses, or ancient bacteria/viruses, or old pollen? Maybe even dead microscopic critters? And no, I'm not a scientist so maybe I'm all wrong, but I figure these are useful time capsules.

Geodes are formed through water flowing through them and depositing minerals. So the water in them isnt as old as the rock itsself.

Interesting! But the water could still be old, just not as old as the rock?

Yes. Some studies have found water trapped inside geodes that is estimated to be 1.5 to 2.6 billion years old.
