Maybe someone can help me out here, but if the basis for Creationism 'Intelligent Design' is that the chances of complex life occuring on its own are infinitesimal, where did the intelligence that created us come from?

If that intelligence is 'eternal' with neither beginning nor end, then what argument can be made that our own design is not similarly eternal?

In other words, isn't the Intelligent Design argument just a sidestep from the ultimate problem of how intelligence, be it human or deific, arose in the first place?
