Allow me to suggest the fundie retort.<quoted text>
Of course it's a religion. Science doesn't actually work. Medicine doesn't work. This computer of yours doesn't actually work. It's all magic!
Bummer is that our 'magic' does stuff and his doesn't.
"Oh, yeah? Well, umm.. Oh yeah? Well, drop your computer in a bucket of Holy water and God will stop letting it light up and stuff, and I prayed to get over a cold and a week later it was gone!! If science is such a great religion, how come you can't explain how the Flood happened? Huh? Huh? So There!"
