This is one question that I HAVE to answer, inasmuch as
many people have no idea where oxygen comes from. Do you have any indication on how many trees have been cut down
and are being cut down in the Amazon? This is where oxygen
comes from, ALL TREES, plus other plant life. Oxygen is a
product of photosynthesis.
All mammals (including humans) inhale oxygen and EXHALE
carbon dioxide. Guess what trees and plants inhale???
Carbon dioxide!. Carbon dioxide is also formed by rotting
vegetation (and I won't tell you what else.)
Ultimately, at the rate we are cutting down trees and
other vegetation, we could have a lot less oxygen on planet
earth.
As far as we presently know, there is no other planet or
star that has oxygen on it.

Yes when a star goes through its final death agonies, it can produce fusion products that are heavy elements, such as Oxygen and Nitrogen, and other gases that make up air. When the star finally dies, these newly created elements, over billions of years, can be swept up by other stars and form parts of new planets. Without this "stellar nursery" the universe would be pretty bland consisting mostly of hydrogen and helium in plasma or gaseous form
Some debunking:
All the Oxygen that is around earth came from this stellar death process. Microorganisms only release the Oxygen into the atmosphere, after chemically unbinding it from compounds that already contain Oxygen

All elements heavier that hydrogen were created in stars. So, yes, stars produce oxygen. The heaviest element that can be created in a star is iron. The exception to this rule is a super-nova. Since we're living on a planet with lots of stuff heavier than iron, you'd be right if you assumed our solar system formed from the remains of a super nova explosion.
Remember that nuclear fusion is what gives stars their energy. Well, what's fusing? The hydrogen atoms fuse to produce helium. Then helium combines with hydrogen and so on. Helium was first discovered on the sun, thus the name (from Helios). When nuclear fusion forms elements heavier than iron, you don't get any more energy out. It absorbs energy, so when a star runs out of fuel it dies. If it's big enough, it goes super nova and creates the rest of the periodic table.

First off, a star is a burning cluster of gas. Most of the stars you currently see are most likely already burnt out. On the other had a planet has an atmosphere that can confine gases and other matter by the force of gravity. A moon is a solid mass that is trap in a planets orbit....

A star is so hot that its fuel, Hydrogen can be fused to form helium.. Planets are pieces of rock that do not produce vast amounts of energy. A planet like earth as micro-organisms like plankton the convert energy into oxygen.

If you see my previous answer you will understand that planets belong to stars. We belong to the sun. The sun is a star.
All the chemistry of the Earth came from the sun or from the cloud of material from which the sun was born.
All the chemistry of all the planets comes from the sun or the primal material.
the only reason our moon and many other moons in the Solar System have no atmospheres is that they are too small for their gravity to have been able to keep gases from escaping.

Just answering to lend credibility to those who said stars can indeed produce Oxygen and Air.
Infact, this is how ALL Oxygen and everything else is produced. Every atom heavier than hydrogen in your body is, literaly, stardust.

Obviously it is a star if it can't produce oxygen or air. Stars are purely made of gas.

All atoms heavier than hydrogen are created in stars. Its gets into space in supernovas and solar winds. Trees do NOT create oxygen, they it split it from the carbon dioxide molecules in the atmosphere.

nope that's the answer
for the reason is that the sun is made of helium and hydrogen so no oxygen can be formed also if the oxygen were formed it will be burned or melted down for oxygen can not survive the heat that the sun forms
