Schecterman,

As you rightly point out 'not exactly "disproved"'.

Certainly one could construct an argument against the existence of god using scientific knowledge. One argument might go something like this:

Science makes certain claims about the world we live in. Religious authorities make certain claims about the world we live in. On balance the scientific view of the world seems [my personal assessment] to give a more accurate and useful description of the world I live in than the religious authorities do. Therefore, in general, I think that scientific pronouncements on this world have more veracity than do to those of religious authorities.

If religious authorities are not a reliable source of knowledge about this world, where I can check and compare their statements with those of scientists, and come to my own conclusions based on the available evidence. Why then should I assume that their statements on religious matters, and the existence of god, have more veracity than their statements on the physical world. If they are not very good at divining the truth in one field, why should I assume that they are better at divining it in another field?

As claims for the existence of god seem to emanate in the first instance from religious authorities, should I not doubt these claims? If I can not put much weight on statements by  religious authorities, then I must look elsewhere for evidence of the existence of god. But I do not see evidence elsewhere. Therefore I will not believe in god, unless, and until some convincing evidence is discovered.

That's an argument in favour of not believing in god, it's not a proof, its just one argument, to be weighed and assessed in conjunction with other arguments for and against. I think it is a good argument, but I don't think that by itself it carries enough weight to be the basis of a firm conclusion.

I believe that anyone seeking a proof, for or against the existence of god, is on a fool's errand. Many people have tried to prove or disprove the existence of god, over many hundreds, and probably thousands of years. To anyone undertaking that project, I wish you luck, but I won't wait up for your result!
