What's the strangest thing that's ever happened in the history of the earth, that we don't know about and will probably never know about. There must have been some pretty unexplainable stuff.

Where all the water came from (serious).

Much of the water is just melted ice.

 

And the rest is just condensed vapour. I don't see what the fuss is about.

 

 

perhaps we should have made like it was a big deal mystery, strung it out for a few years by measuring stuff and staring at data and got a billion dollar research grant

According to general relativity, wouldn't it be the singularity like everything else?

General relativity doesn't cover special cases (the clue is in the name) :)

 

The only thing we can be confident on concerning the start of spacetime is that a lot of energy appeared. Inflation occurred causing matter to condense from that energy, but the baryons alone could only have formed the elements hydrogen and helium (and their anti-particles and isotopes). Oxygen needs several steps of fusion and therefore requires stellar activity. So the earliest possible water would have taken at least 200m years from the inflation event to form (the age of the earliest stars).

 

However the question asked about Earth. It's a mystery where the water on Earth came from. The most recent accepted theory was that it was delivered by comets at some point after the impact which created the moon. Our recent comet encounter with comet 67P shows that if it was, then something is broken in our understanding of water. Or that particular comet is in some way unusual. A mystery.

True. The amount of water in those is large enough that we can probably observe its composition from here and I'm not aware of a theory (rather than hypothesis) that purposes a common origin for water in both places.

There is enormous quantities of water ice in the solar system particularly in the Oort Cloud, but no mechanism to deliver the quantity we have on Earth.

Well, there you go then. That proves that God did it.  ;)

So discovering that the water on 67P is different water to earth's water totally shifted scientific understanding.

 

And, there was me thinking it was all about a shirt.   :)

It failed to support the prevailing theory, yes. The shirt was almost irrelevant :)
