To find out, scientists turned to chemistry. Here on Earth, about one in every 3,000 molecules of water is made with a deuterium atom instead of a hydrogen atom.
A deuterium atom is similar to a hydrogen atom except that its nucleus contains a proton and a neutron, instead of a lone proton. (Both atoms also contain a single electron.) That makes deuterium twice as heavy as hydrogen, which is why water molecules made with deuterium atoms (HDO) are known as “heavy water.”
At the time that our sun was born, the ratio of deuterium to hydrogen throughout the universe was about 1 deuterium molecule to every 100,000 hydrogen molecules. But for water in the solar system, the proportion is significantly higher.
Water with a high deuterium content can only form under specific conditions. The environment needs to be very cold, and there needs to be enough energy to power the reaction that binds hydrogen, deuterium and oxygen. Over the past several decades, researchers have come up with two possible — and competing — explanations of how this heavy water took up residence in our solar system.
The first is that it came from interstellar water ice that formed in the huge cloud of gas that gave birth to our sun and the solar system. Stellar nurseries can be found throughout the universe, and they are rich in both heavy water and regular water (H20), the researchers said.
The second possibility is that the violence and energy of star birth ripped apart that interstellar water, and its building blocks got reprocessed within the protoplanetary disk that would eventually coalesce into the planets and other heavenly bodies.

“Not a drop of water has been created or destroyed”
Now that is just plain nonsense. Water is created and destroyed routinely everyday. I’ve done both quite often. Put hydrogen into the air with its oxygen and light a match, the resulting fire combines the hydrogen and oxygen to create water. Put water into a flask with an electrode powered by an electrical battery and you dissociate the water into its constituent hydrogen and oxygen gases. Plants routinely create and destroy water molecules.
“No, she is relying on conjecture masquerading as hypothesis.”
No, it is an observable and measurable property.
scuse! true!
more accurately none of the elements that compose the water on earth have been created or destroyed since that creation
and there is a finite amount of those elements on earth from which water can continue to be formed (barring those that may yet arrive from deep space)
Now - please continue combining and ripping apart those H2O molecules at your pleasure! As those elements disperse into the atmosphere they do seem to have a way of finding each other again, and ending up back in the beakers of your lab!
I have considered that we are breathing the air and drinking the water containing elements that were expelled by prehistoric creatures, or expelled from the lungs of Mozart, Newton, Hitler, Stalin - and Christ
I’ve always enjoyed a splash or heavy water in my single malt Scotch.
The only thing “hateful” I see on this thread is you making judgements and calling people names...
Take a moment and reflect.
“more accurately none of the elements that compose the water on earth have been created or destroyed since that creation”
Unfortunately, that statement is also entirely false. Atoms of Oxygen are being created and destroyed all around us everyday, and atoms of Hydrogen are being created around us everyday as well. The destruction of Hydrogen atoms does occur, but it is a rare event in our immediate Earthly environment, but occurs elsewhere in space where anti-matter is created in stellar fusion events and annihilated into pure energy by contact with matter such as the ubiquitous atoms and molecules of hydrogen matter. This is all part of the matter can be converted into energy, and energy can be converted into matter, such as Hydrogen. The Hydrogen can then be converted into Oxygen.
Yes, offending people is a good way of getting them to check their premises, to re-evaluate their logic, and to review their conclusions.
Using facts and air-tight logic, on the other hand, is a very ineffective method of refuting their arguments and of getting them to change their thinking.

>> This is a hypothesis
... stated as though it were a fact.
>> Does tis sort of thing make you nervous?
Not per se. Science and the Creator are compatible (because the stuff of science — physics, chemistry — are His creation too).
What makes me nervous is when hypotheses like these, especially flimsy ones, are passed off as Facts Chiseled In Stone and carried forward into “policies” and “mandates” that destroy our economy and our way of life, in the name of earth or universe worship. That’s idolatry, by the way — worshipping the creaTURE rather than the Creator.
The earth is older than the sun? LOLOL!!!!
Gen 1:2
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.
According to the KJV version, you could read that God created water first.
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.
I'm no young earth creationist but I'll give credit where credit is due.
Supernova. Every atom in our solar system (with the possible exception of hydrogen) were created by the explosions of stars much bigger than ours billions of years before.
Isn't Creation wonderful?
Which is why I was replying to post 8 which asked "Didn't the sun come first?"
In other words, play it safe and stick to beer.
I stand corrected :-)
I can see that a lot of water molecules probably survived the solar nebula collapse. But a hell of a lot of them were destroyed in that same process.
What came first? The bum’s drunken stupor, or the hooch he chased it with?
Happens in us, too. Love Bio.
