This has been bugging me. We cannot breathe in outer space, so instead of air being out there, what is? Is it air that we just can't breathe due to the lack of gravity? Or how does it work? Please help me out haha, very itching question. Thanks!

As lithium man stated, space is a near perfect vacuum, meaning the average cubic yard of space contains only a few atoms at most. Space everywhere contains radiation and light (photons) given off by stars. There are also the theories of dark energy and dark matter as well, which are believed to make up a very large percentage of the universe, which would also fill the void that is space. I would Wikipedia those topics if you want to learn more:
http://en.wikipedia.org/wiki/Dark_matter
http://en.wikipedia.org/wiki/Dark_energy
So basically, there is radiation, photons, the occasional atom, and possibly dark matter and dark energy in the emptiness of space.

We can't breathe in space because there is almost nothing to breathe. Space is a near-perfect vacuum. There are a few atoms per cubic meter, even in interstellar space, but apart from those atoms, and some photons (light), there isn't anything filling space.
There is most certainly gravity in space. You are weightless when in orbit because you're in free-fall, not because there's no gravity. If there was no gravity, the Earth would fly off in a straight line, instead of orbiting the Sun.

Space is filled with an extremely thin hydrogen gas.
Not being able to breathe in space has nothing at all to do with gravity. It has to do with the fact that space is almost entirely an empty vacuum, and the hydrogen that *is* there wouldn't do us any good anyways.

Space has the virtue of being able to sustain and separate matter.

Nothing. It's empty. That's why it's called "space" and not "stuff".
You don't need gravity to breathe air.

"so instead of air being out there, what is?"
NOT air hahahahahahaha
That's why. We need air to breathe.
NOT air hahahahahahaha
That's why. We need air to breathe.
