Organization is an incomplete superset of, not subset of, intelligence. Ergo, SETI is right to rule out organized signals that coincide with a star's rotational speed, for instance.

When you find a theory with some measurable explanatory power, do let everyone know.
Until then, intelligent design is (at best) quaint speculation on the order of how many angels can dance on the head of a pin.
