Question about oxygen...true or false?

Hydrogen was created in the big bang universe about 14 billion years ago. Oxygen was synthesized billions of years later in the interior of stars.

TrueQuestion about oxygen...true or false?
Oxygen was produced in the interiors of the first stars, which astronomers called Population III stars. These stars were different than the ones around today because they formed from pure hydrogen and helium, and because they do not absorb radiation as efficiently as heavier elements do, these star were much more massive and luminous than the super giant stars existing today. They were thought to be as massive as 500 Solar masses, and when they began to fuse oxygen and carbon, they exploded as supernovae scattering large amounts of carbon and oxygen that got into and still exists in the very old Population II stars that make up globular star clusters and the halos of galaxies. Since then, generation after generation of stars continued to make oxygen and expel it into space when they expire. Therefore, the oxygen in the Universe today was produced continually over it's lifetime.
Because oxygen is a heavier element that hydrogen, helium, etc... it would have been synthesized is star's interiors billions of years ago. At one tome Earth had an atmosphere with a very high oxygen content but when the planetesimal collided with Earth to form the Moon the Earth's atmosphere was completely wiped off the Earth. The 2nd oxygenated Earth atmosphere came from ocean living cyanobacteria which after eating gave off oxygen which went into the Earth's atmosphere and then allowed sea life to move on the solid Earth surface and evolve.
True





Elements heavier than Iron were formed even later in the explosions of Supernovas.





Our star, the Sun, has heavy elements in it so it is a second generation star formed from the reminates of earlier stars.
True but it was only tens of millions of years before oxygen came along..

No one knows this for a fact. But I think the theory is all did come from dying stars yes...
True.
True
It's True. :)
true.
more likely to be true
