Prove to me that there is no Allah

No, I was born a Muslim but not anymore. I tried quite long and hard to remain a muslim, went through denial first and I tried to find answers from many websites, many scholars and met some really brilliant/nice muslims as well as some jerks on the way. But I never found asnwers, I only found justifications.

Leaving your religion (Islam) is very hard decision because in a country like Pakistan, even your close family and friends cannot comprehend or respect that. Unless you hide your beliefs, you can easily be socially outcast and some people even threatened violence. People assume that the person is misguided or ignorant but just cannot seem to comprehend that someone who spent years studying not only Islam but other religions and theology in general, can believe in anything other than Islam. One of the typical response after they find out that I know what I am talking about is to question my intellectual honesty or my reasons i.e I am just doing it for the "worldly pleasures" or that "my heart has been sealed", etc etc. The monopoly that some Muslims claim on "absolute truth" is one of the biggest turn offs for me.

However, some muslims that I met, acknowledge the fact that our faith or belief is our "opinion" about some basic yet complex human questions. They have complete faith in Islam but acknowledge that everyone can reach a different conclusion on their soul searching quest. This is not George Bush's "With us or against us" war.
