Evidence for God from Science

Hey guys, I am currently in the process of creating short comic strips that correct the ignorant view athiests have towards Christians and Christianity (such as the things on godisimaginary.com )

But Im stuck on something. Their first "proof" is that when you pray, let's say to cure all cancer, nothing happens.

I know they're wrong, but I don't know how to refute this. Please help me.

The old "God is a genie in a lamp" belief. Just ask the genie what you want, and every desire will be yours. Cancer, and physical death are part of the "circle of life". Without death, there can be no life.

A good one would be Jesus, sitting in heaven, hand over brow (oh brother). And some saying, "God if you'll appear to me, fix all my problems, etc. I'll believe in you. In jesus name, amen!"

"My name's Jimmy, and I'll take all you can gimme!" People make the mistake of believing God works on some kind of formula: "Do good, God rewards me with good things. Do bad, God gives me nothing." Truth is, God doesn't owe anybody anything.
