There are no plants there to make it.

Actually, there is oxygen in space, however, the majority of it has already been captured gravitationally by stars, planets, or other celestial bodies. So space is *almost* a perfect vacuum, but gas and dust particles do float around out there. These particles are referred to as the interstellar medium by astronomers.
According to Thomas Arny's "Explorations: An Introduction to Astronomy," if we were to compare the amount of gas in interstellar space to the air we breathe, it would be like "one marble in a box 5 miles on a side compared to the same box filled completely with marbles." So needless to say, there isn't very much oxygen in outer space, but there is some. And the reason there isn't more is simply that the gravity of all the other various celestial objects out there, including galaxies, has captured most of the gas and dust.

There is oxygen in space ... just a very small amount ... and it is very reactive with other elements so free oxygen, 02, disappears very quickly in chemical reactions.
If there were no oxygen in space how would we have oxygen on Earth when it was formed?
I think the answer you want is that it basically is bound up in other compounds that it has reacted with so there is a very small quantity left in space which has not reacted with anything.

There are trace amounts of oxygen in space. But there is no atmosphere to space, like there is on earth, to hold the oxygen in. Most of the oxygen on earth is made by plants, and there are no plants in space either. Since there are no means by which to produce oxygen in space, and no means to contain it, there is considered to be no oxygen there.

Oxygen comes from plants, which are severly lacking in space. Gravity holds what is produced on earth close to the surface.

The gravity of planets draws the oxygen into their atmosphere. Space has no gravity, so oxygen has no reason to leave the atmosphere.

YALL SAY THERE'S NO OXYGEN IN SPACE? Well, you're right. Not only is there no oxygen in space, but there's no matter too. That's the definition of space, no matter what (get it?).

because oxygen is a byproduct produced by plants when they make photosynthesis. plants expell the oxygen from their inside while making themselves some food. so there are no plants in space, therefore nothing to produce oxygen.

I think it is because space doesn't have an atmosphere to hold in any oygen or nitrogen. For example Earth has an atmosphere made up of like 21% oygen, and 78% nitrogen and 1% other gases and gravity hold the atmosphere!!!

because there isn't enough oxygen to fill up the entire universe, so you get little pockets of oxygen (like earth's atmosphere), and the rest is empty.
