Intelligent design means that the universe behaves in accordance with known or unknown "laws". For example, Einstein's General Relativity would be such a law. However, it is known that this theory does not apply to the microscopic world.
If the universe were intelligently designed according to Laws such as the laws of classical physics, then such laws or other similar laws should also apply to microscopic physics.
What is the nature of these similar laws? Well, if a number of systems are identical and have identical initial conditions, then classical laws would deem that they behave exactly the same. If the microscopic laws are similar, or if they are of intelligent design, then we should expect exact behavor from identical systems.
However, on the microscopic scale, what we measure is that identical atoms, excited to the same state at the same time, will not decay at the same time. The decay time is probablistic. The laws of probability apply, which are based in large measure on randumbness, not intelligence.
This does not imply the lack of a gods, or gods, or even the supernatural- just a lack of intelligent design. Perhaps the god(s) are learning from us as we discover more and more about the universe. The behavior of gods recorded in human history would be evident of such a case.
