i know that is no air on the moon but does that mean that we can not literally "breath out" and " breath in"?

Yes. The first responder is not correct -- the moon has no atmosphere whatever, as its gravity is too low to retain any sort of gaseous atmosphere, so the only gaseous molecules found there are those that are found in interplanetary space generally -- principally hydrogen expelled from the sun. So, you could breathe out -- but you couldn't breate in.

You'd breathe out, whether you wanted or not, holding your breathe might burst your lungs from the pressure differential.
After that I'm not sure if you can breathe in or not, I think much of breathing in has to do with air pressure. After your insides and your outsides equalize your diaphragm can still work I suppose, maybe you'd make a weak fluppering minimal kind of lung breathing. Really more like flapping your sail really, you'd breathe nothing.
The lung mucous and saliva and sweat and tears would boil though, I heard you can stay concious for 13-14 seconds in a vacuum, or half that if you're panicked, and after that your vision will go gray and blurry and you'd black out. You'd start becoming brain damaged after too long, and die in a few minutes (and get sunburned) You won't explode. You'll get a killer ear pop.
Explosive as opposed to rapid decompression is worse for you though. I don't know what would happen if your spaceship exploded.

Without air or atmosphere, humans cannot literally breath in the nothingness. But humans can breath out their initial air lung capacity.

There is air on the moon, it just not made up of the same gases as the air on earth, so you can breath in and out.

I'm sure you could work your diaphram muscles right up until you lose consciousness. It would do no good, but you could move them and thereby compress and expand your lungs. Of course, if there's nothing to breathe, would it really be called breathing?

well your lungs will still function (the movement of the muscle) but with no air. maybe they didn't mean it literary. if you could provide us with a source of this quote it might help with an answer :)

You might be able to breathe out once, but then you're dead.
