If we take some of the laws of physics too, we can write these down very succinctly using mathematics, indeed mathematics seems to be a language that is superb for describing things in the universe, a fine example being Maxwell's equations for the electromagnetic field. Theoretical physicists often say they feel that they are discovering these laws too:

So if the universe can be described in a language like mathematics doesn't that too strongly suggest an intelligent source? much as we'd infer if we stumbled upon clay tablets with writing on them or symbols carved into stone? Doesn't discovery of something written in a language, more or less prove an intelligent source?

So isn't this all reasonable? is there anything unreasonable about this position?
