The overarching goal of all Buddhism is to end all suffering. A being knowing all causes and all effects is therefore, per Buddhist definition, obliged to act in a way that will bring enlightenment, i.e. the end of suffering, to another being. The latter then must act in the same way. What ensues is an exponential increasing number of beings causing the end of suffering of the unenlightened. As the latter is a finite quantity, there will be no more suffering being at some point in time. Therefore we can prove the theory of existence of an enlightened being wrong if there is no enlightenment in a finite amount of time. As an enlightened being knows all effects it should know how to cause enlightenment in an unenlightened being in the shortest possible amount of time, because there should no unnecessary suffering. Therefore the remaining time to the extinction of all suffering will tend to be near zero. From this follows the enlightenment of all beings should have already occurred or should occur in the next moment. If it does not, the existence of an enlightened being is refuted.
