I personally believe that it would be naive thinking that we were the only living things in this universe. However i do not believe aliens have come and landed on earth. My reasons for this is because what would they breathe? We cannot breathe on their planet so how would they be able to breathe on ours since they obviously do not breathe oxygen like us.

Yeah, most definitely. We're certainly not the only ones out there. I do believe they've came to Earth though, there is definitely something which the Government is hiding.

Landed on earth and walked or just UFO'S?

UFO's, maybe crashed.

Taking in to account that astronomers so far have found over 500 unique solar systems in our galaxy, I'd say it's more than unlikely
that Earth is the only planet with living organisms or intelligent life on it for that matter.

So my answer to this question is yes, I do believe extraterrestrial life exists.

The chance that there exist other creatures out there on different planets is high. Though I do not thing they are of a super advanced race, or just alike us humans. Frankly, a "alien" could just as well be a mindless dog like creature living on a planet for all we know. If they had been super-advanced, and capable of space travel then chances are also high that they would have arrived at Earth already and if they had done that then there would be no logical reason to keep said fact hidden, nor do I believe that an advance alien species would bother to keep it hidden just because someone asked "really nice".
