There are many living things on earth that do not "breathe" oxygen (They do include oxygen as part of the materials that make up their bodies, in proteins and in water that is within their cells). Say, for instance, all anaerobic bacteria.
Living without water would be much harder. It is really a very unusual compound that is quite different from any other common liquid. The unusual properties of water are very useful in allowing chemical reactions to take place that are needed for life. There are some living things that can survive for very long periods without taking in liquid water - but that doesn't mean that they don't need water. They have water in them, in their cells, and they absolutely need to have water within them to be alive and grow and reproduce. There are no living things on earth that do not have water within their cells.
I think its very much more likely that any alien life will use water, than use any other kind of liquid. But there might be alien life that exists without breathing oxygen.

as u know that theres a myth that alien exist,so they do not need water or oxygen to live,but the reality is that life cannot exist without water and oxygen thats why origin of life is only found on earth not on any other planet

I won't say its impossible, but there isn't a chemical anywhere that acts like water--it's unique. My guess would be no, but who really knows? There may be another solution to respiration and other chemical reactions life requires that doesn't involve water.
If you are just trying to write some sci-fi, just say they are methane based organisms with a different chemistry. Even if you bothered to figure out how that could happen, explaination of the chemistry would be a boring read, so use your artistic license to leave that part out.

There is life right here on earth that can't survive in an oxygen atmosphere. And there is life right here on earth that can survive for years or even decades without liquid water.
So anything is possible.
But life on another planet that breathes other gases may not be recognizable to us until we physically get there.
I also just thought of something - why do you assume life on another world would have to "breathe" as we do?
Insects don't breathe they way we do, neither do plants or bacteria.

There is life near vents in the ocean that don't use oxygen, but methane, they do however exist in water.... There may be some life forms that use another liquid.

Yes, definitely.But the organism must have some other living process system which does not need combustion process for energy requirement.

Well it wouldn't be life as we know it but when you get into life as we don't know it I guess just about anything is possible.

It is possible, just because we breath it doesn't mean other organisms and other life have to breath O2(Oxygen). Plants don't breath O2 they breath CO2 (Carbon Dioxide).
