I believe that God can not be absolutely proven by deductive reason or experience.

And this ...[text shortened]... blem with atheism then is that is can offer no further help in understanding the world or man.
You started out well here, but contradicted yourself and ended up very poorly. You started off correctly by saying that,
"atheism is simply the disbelief in God or any deity." That is true, and I will give you credit as being the rare breed of theist who recognizes (or even understands) that fact.
You say that in one breath, but then inexplicably fall back on the standard theistic misconception of claiming that atheism is a belief (in the non-existence of god). In fact, you contradict yourself within the same sentence by saying,
"They (atheists) don't believe, Christians do believe - both are perfectly reasonable beliefs (!) because both are unprovable." You make the same blunder in your closing paragraph by claiming that both "beliefs" are reasonable.
You are savvy enough to give your argument some semblence of depth by introducing a correct definition of the atheist's position, but you then fail to incorporate that position into the body of your argument. For your benefit I will restate it for you: atheism is not a belief. It is a lack of belief in theism. Theism is the belief in a god or gods. An atheist is someone without theism.
The theist would have us believe that there are two competing beliefs on the table (theism and atheism) and that one is just as reasonable as the other. But this is completely false. There is only one belief up for consideration, namely the theist's. The theist is the one making the active claim that there is a god. As the one making the claim, the burden of proof lies entirely upon the shoulders of the theist. The atheist is merely one who has considered the theist's claims and who has found them to be lacking. So we are only considering how reasonable the theist's beliefs are. If his beliefs are unreasonable then that is the end of the story. There is no other belief to consider.
You are also correct in saying that atheism confines itself to one question only; which is whether theism can be justified or not. But then you try to insinuate that this is some kind of shortcoming for atheism; that atheism is somehow lacking because it offers no explanatory data. This is merely a function of the word itself. Atheism simply means to be without theism. It offers no other content. But atheists have access to as much explanatory data as theists do. Evolution or the Big Bang are explanatory hypotheses typically found in conjunction with atheism which are not logically contained within the definition of atheism itself.
So, to argue the relative merits of Evolution vs. "Intelligent Design" as explanatory systems might be an enlightening pursuit. But to argue the relative merits of atheism and theism as beliefs is neither enlightening nor even possible. Between the two, theism is the only belief being offered up for consideration. It has to sink or swim on its own merits.
