Did the Earth form before the Sun?
I've read somewhere that the water on the Earth is older than the sun? Is this true
-------------------------------------------------------
answers:
YKhan say: The Sun was formed first, and the planets came a couple of million years later from the left-over materials around the Sun. The materials that formed the solar system would've included water from a previous generation of supernovas. The hydrogen is the oldest material in the universe, and oxygen is about the 2nd generation of materials. When the oxygen and hydrogen got together to form water, they would've been a 3rd generation material. The Sun is way younger than that level. But it's not really useful to compare the age of the materials to the age of the solar system, as the materials would always have to form first before the solar systems.

busterwasmycat say: can't really age-date water. However, all the matter in the solar system, including the matter now in the sun, was around before the solar system formed, so the water (and there was water in the nebula, the cloud) would be "older" than the sun. Older than the earth too, of course. Water doesn't stay permanently as water, though, because it can and often does react into other things, and get remade by back-reaction and it gets kind of hard to say what the average lifespan of a water molecule would be. The idea of water being around before the sun, and some of that water still being here, that is a likely true statement.
It isn't even certain whether the water on earth came very late (from comets) or was with the earth when the earth formed, and just migrated out from inside (which it is still doing), or a bit of both.
The earth though, did not form before the sun. At least not according to how things are thought to have happened.

duke_of_urls say: Well, that's a fuzzy matter, I think. Current theory is that the Solar system formed from a huge cloud of gases and star dust; mostly the gases. This whole thing gradually collapsed because of gravity. Somehow, in the process, rings of material formed (is that when the Earth formed?), and those somehow further coalesced into the planets. At some point, the Sun got enough pressure and temperature to begin fusing hydrogen, it became a star. Is that when it formed?
I don't think there's an exact way to say when a bunch of gas and dust formed into a star and when a bunch of it formed into a planet.
Probably the Sun was more in its current form before the Earth was in its current form, because it looks like the Moon may have formed when something crashed with whatever was in Earth's orbit. It's very likely that the Sun was already fusing by then.
So when exactly did they form? There's no 'exact' in matters of gas and dust.
So, back to the water on Earth. When did it form; when it became a liquid on the surface of the Earth, or when it became a water molecule? It is certainly possible that Some of the water molecules that are in the oceans are billions of years older than the Sun!

Dan say: They kinda formed together out of the same gas cloud. The sun ignited before the earth, though, and pushed away the excess light dust leaving the rocky inner planets.

say: Soil of Earth was tested before the sun was able to be measured. Like a corn stalk can be measured faster than you measuring a man on the other side of the world.

Clive say: Congratulations on totally failing to understand. The Sun formed first. But the elements and compounds existed before that, and THEN became part of the Sun and planets.
-
Joan H say: There is a lot of water in the universe that was there long before the sun or earth were formed.
-
Robin say: no its not as every atom on Earth was formed in the sun
-
say: < Did the Earth form before the Sun? >
No

The Mikel say: No one knows.
The "scientists" can only guess.
We have come to take what a "scientist" claims as Gospel.
It has become almost a religion of its own.
"Scientists" are people who follow a method, and publish papers books.
We the people Trust them, and cannot argue when "they" make a statement to be "fact".
