You might be a practicing but non-believing atheist.

Good point about creations not necessarily being comprehensible to their creator.

Communicating by changing physical constants strikes me as even worse than trying to use words. Of course, I'm living on this level, but even if the local creator is getting comprehensible changes in physical constants from It's next level up (I find this unlikely, but I could be wrong), that doesn't mean we could be communicated with that way.

Changing the physical constants strikes me as a good way of breaking the whole experiment, but people do that sort of thing all the time.
