This is a really inane statement. I mean, the answer is right there in front of you. We can build appliances that reliably use those "unseen waves". We can replicate the results easily. We can control it and make it work for us in a predictable fashion.
God doesn't work that way. We can't duplicate a god's actions. We can't harnass its power in an appliance and make it work for us at a predictable time and place. We can't even make it work reliably through prayer or any other mechanism. Effects cannot be repeated if we claim they work the first time. What we are left with non-replicable events, unpredictable events.
Do you see the difference here? We understand the "unseen waves" because they work in a predictable fashion. We can't understand (or even know that it's really there at all) this "god" power. Indeed, if we could control it, it would cease to be supernatural, wouldn't it? You never hear anyone claiming that electricity or light is supernatural, do you?
When you define god in such a way that it is impossible to understand, impossible to replicate, and impossible to control, what you've done is define god right out of existence. Because he simply isn't needed to explain those "unseen waves" and he isn't nearly useful enough to even run an appliance. What then is the point?
