How might I test . . .

The same way you test your own inferences that an intelligible universe may be a product of non-intelligent non-design. Do you not realize that all science begins with untestable assumptions? If not, then you have adopted an untestable assumption of your own.

I have made no such inferences, and as such I have no such tests.

Do you not realize that all science begins with untestable assumptions?

The starting axiom of science is that the fundamental properties of the universe do not change. All else is derived from observation and is testable. Are you admitting that your claims are untestable? If so, then they are not scientific, and it is not honest for you to claim that they are.
