Proof that god doesnt exist

Ok, here is my proof that God does not exist. Here are some qualifications to that statement: right now, I am only talking about the Judeo-Christian-Islamic god. I don't believe in other gods either, but this one is just so easy to disprove. Another qualification: Though I did come up with this by myself, I know that I'm not the first person to do so. Please don't flame me just because its not 'original', remember that this is my opinion.

The conception of God that most people around the world have simply cannot exist. First, let me define what most people think of as God: An all-powerful being, who created the universe, who is all-good. Now, you would think that a universe created by such a being would be a wonderful place to live in. Of course, as we all know, this is not the case. Innocent children get raped by pedophiles. Criminal CEO's rob people of billions and get away with it. People in third world countries work their asses off and yet they live horrible lives. If God is both willing and capable of stopping these perversions of justice, then why doesnt he? The answer, of course, is that he doesn't exist.

No religious person has EVER given me a satisfactory answer to this dilemma. Here are some of the crappy arguments they have made:

1) God does not cause evil, the Devil does.
OK, this one is perhaps the stupidest one. If you believe the Devil is capable of subverting God's will and causing evil, then you believe that the Devil is as powerful as God, and you shouldn't call yourself a monotheist. Plus, if the Devil can do whatever he wishes despite God's will, then God is not all powerful. Therefore this argument doesn't fly,

2) God is all good, evil comes from man's free choice.
I don't buy this one either. God created everything (according to the religious people). Therefore, he must have created both humans and free will. Now why would he create free will if he knew some men would choose evil? You might say that evil people turn away from God, so he has no responsibility towards them. Ok, fine. But what about the innocent, good people that are harmed by the evil people? Doesnt God care? Of course not, because he doesnt exist.

3) Evil exists in the world for reasons we don't and CAN'T understand. God's reasons are unknowable because we are mere puny humans.
This is probably the best reason, but I still don't buy it. According to this statement, you are supposed to just accept evil because you trust that god has a reason for it. Now, I simply can't accept this. Why would God give us intelligence if we weren't meant to use it? If God simply intended for us to be herded around like sheep, why didn't he make us sheep? The answer, of course, is that God did not make us, because he does not exist!
