I wrote a paper on the problem of evil recently. I condensed the the argument into:
-God is omnipotent.
-God is against evil.
-God could prevent evil.
C: This is not the case, therefore God does not exist.
I argued that the problem of evil isn't wrong, but that the definition of God is in error.
Therefore, the definition of God needs to be redefined. Either God is not omnipotent, or God is not against evil.
I personally feel that it could be either, and that the chances of it being either are quite possibe (in my personal belief both are wrong). To remove the problem of evil I only need to redefine one of those, however. This is best at keeping our optimistic hopes! I believe (from analogy) that God is not omnipotent. The basis of my view is that nothing that I have seen or believe to ever exist in nature is all powerful. Therefore to assume that ANYTHING out there is omnipotent is a tad absurd. However, I believe that I am against evil, and therefore something in nature is against evil, so the possibility of God being against evil is more likely.
Then again, people would question whether our Creator is a "God" if she isn't omnipotent.
I'd like to say: Yes!
