Any water originally on the planet must've boiled off during the Earth's molten period, right?
Well, that's the old theory...
Well, I don’t exactly know how our water got here, but this I do know, God made it and He put it here on our round planet. Exactly how He might have done this is a fascinating question, and I think it wonderful that our scientists are slowly, sometimes with missteps, unlocking the secrets of the universe.
Presuming there was a molten period.
Occasional Cortex: “Most of it came from the tap.”
I don’t see how either theory explains the water/ice elswhere in the solar system such as on Jupiter’s moons Europa and Ganymede.
Well, does this means that the oceans are rising (assuming for a minute that they are) because of unseen comet strikes continuing even today?
That theory never passed muster with me. Glad I’m not the only one.
My understanding with that theory is that the planet would have required far longer to cool than appears to have been the actual case.
Comets consist of heavy water. Icy asteroids are more like regular H2O
Think
It came from Culligan comets.
Those bodies formed beyond the “snow line.” There was plenty of molecular water in those regions long enough to result in the amounts of water ice there.
In fairness, the cometary impact blue planet theory never felt right to me. I was happy to see this theory evolve.
That's too hard.
Considering lava, it seems like you might say that the majority of the material inside the earth is molten today.
Hydrogen is the most abundant (75%) element in the universe and oxygen is the third-most abundant (1%).

Water us composed of hydrogen and oxygen.
Any questions?
That seems like an awful lot of comets and asteroids....
“1 In the beginning God created the heaven and the earth.
2 And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.”
We don’t need no steenking comet.
Except for climate change. That's settled. /sarc
No, due to the pressure within the mantle and even between the crust and the mantle. The asthenosphere, for example, is generally solid due to that pressure; it’s actually when the pressure goes down that molten magma can form, as I understand it.
Also, the planet’s outer core is liquid iron and nickel, but the inner core is solid; but the temperatures down there are as hot as the sun’s surface.
You said it faster than I could have. Just found this thread.
