My point is, that if God exists, Stephen Fry is no intellectual match for him. I can't answer the Problem of evil in the world, But there are many approaches that try to, and Stephens approach is full of arrogance, although I see nothing wrong with that line of enquiry and to even suggest God created a world with injustice, is a valid enquiry. I believe his arrogance in calling God stupid, isn't justified.
Seriously, think about it. We are hypothetically giving God exists, then is Stephen Fry more intelligent than God? No.
My answer to the accusations of Stephen Fry would be,
There is injustice in the world, Because God chose life.
God could not chose life as we know it without the potential for evil. Otherwise he would have created robots and wrapped them up in cotton wool.
Do I agree with it, No, but then again I am not God, and am not foolish enough to suggest I know more than God.
