Scientists may have discovered unexpected cosmic origin of Earth's water

Five billion years ago, the universe was Earth-less. It remained that way till a vast number of asteroids smashed together and compacted into a giant rocky orb. But that raises a question: The Earth's surface is 70% water, so where'd the liquid come from?

A long-standing theory is that a water-rich class of asteroids, called carbonaceous or C-type asteroids, could've pelted the Earth during its creation and brought along water. There's a caveat though, and the C-type asteroids may be only half the story....

IF all the planets were formed at the same time, were the oceans on Earth, said to form in less than 150 million years, the result of dust created from the proto-earth collision that created the Moon? (4.5billion yo earth; 4.4 billion yo oceans) https://ocean.si.edu/through-time/ocean-through-time

[BradyLS]

A theory I read long ago suggested that icy comets hit the earth to supply our oceans.

NASA never analyzed the moon dust for composition and thought about this decades ago?

Part of me calls BS, but I’ll settle for hard science: I want to SEE water from dust.

[\/\/ayne]

Yes, I remember about 4 billion years ago when the water-bomb meteors were just tapering off. I almost stepped in a poodle.

Where did the “vast number of asteroids” come from?

I want to SEE water from dust.

Real estate developers in Las Vegas believe it can happen.

[Fai Mao]

The even vaster Ort cloud and closer in asteroid belt between Mars and Jupiter.

Where they came from is not really an issue.

SHEESH

They DID say "cosmic", right ?

. . . and everybody danced all around God.

My kids learned about the third day in 1st grade Sunday School . . .

Hydrogen is the most abundant element in the universe. The second most abundant, helium, is noble and doesn’t form molecules, but escapes into space instead. The third most abundant is oxygen, which combines with hydrogen to make water. Water is the most abundant molecule in the universe, which is why we have so much. There are whole moons in the outer solar system made of it.

...Water is the most abundant molecule in the universe, which is why we have so much. There are whole moons in the outer solar system made of it.

So maybe the question to be asking is not "Why do we have oceans?", but "Why don't we have more oceans?" Possibly even to the point of covering the entire earth.

[Telepathic Intruder]

The reason for that is most of the lighter elements were pushed out of the inner solar system by the early solar winds. That’s why gas giants like Jupiter and Saturn which are mostly hydrogen and helium formed in the outer solar system, and denser rocky planets formed in the inner.

“Watch out for that puddle!”

[vpintheak]

Twisted-pretzel logic attempts to explain that somehow, some way, it had to be a cosmic accident that made it all happen. And atheists mock people of faith.
We have it laid out for us already. There may be questions of when, but the how and why are easily obtainable.
