What testing do you think should be done to support or falsify this hypothesis?

I'm content with the trillions (likely much more) of tests going on outside the front door right now.

I suppose one could observe other tests in other places, even on other planets. More testing is good. Successful tests justify higher confidence in the hypothesis, and if the hypothesis fails, the results can be used to continue the search for truth.

What evidence/test result, should it occur, would falsify your hypothesis?
The presence of a regulated moving part on an object that was not the result of intelligent design.

If it'll cheer you up, there is plenty of potential for debatable results. A solenoid could become entangled in some mattress springs and a battery could alight just so and... I'll not worry about it until it happens.

For my own edification:
1. Define regulated moving part.
2. Define intelligent designer.

Thanks
A regulated moving part is a distinct physical subset of the object, capable of controlled changes back and forth between at least two positions, or in a circuit, relative to the remainder of the object as a result of force(s) applied by other parts of the object, while maintaining its status as part of the object.

An intelligent designer is a thinking entity with the capacity to form plans.
