Water on our planet, where did it come from?

A water molecule is created when two atoms of hydrogen combine with one atom of oxygen. W

The volume of all water (on our planet) is about 332.5 million cubic miles (mi3), or 1,386 million cubic kilometers (km3). A cubic mile of water equals more than 1.1 trillion gallons. A cubic kilometer of water equals about 264 billion gallons (1 trillion liters) https://tinyurl.com/fxa4yn69

When the water on our planet was created, how much energy was released?

    $\begingroup$ As well as Earth's water came from space, but not in the way we thought. $\endgroup$

    $\begingroup$ I’m voting to close this question because it seems likely to be AI generated... fairly non-pertinent stats (that they don't connect) and random connected link without explanation? And just the tone doesn't sound particularly human to me? $\endgroup$ Nov 5 at 6:18
  • $\begingroup$ This post contains at least two questions at once. If it were about the origins of water on Earth, it would've been a very broad question since there are multiple hypotheses. If it were about the energy released during formation of 1.4 million km³ of water that would've be an entirely different questions. The first one with a bit more focus could be on topic on this site. The other one is more of an astronomy question about origins of water in the Solar System. $\endgroup$ Nov 6 at 10:31
