What would it take to change your mind?

[Darwinian]

But why should we need to pray at all?

Does God look down at a sick and dying child and say to himself "I'm not going to do anything unless someone prays to me for help. And even then I may just ignore them?"

If that's the case then what's the point? And surely if God is omniscient then he already knows the outcome of all events and so prayer is pretty pointless as you can't possibly influence him can you?
