Does complexity require intelligent design?

Everytime this subject of ID comes up a pack of Agnostic and Atheist decend upon it like wolves. ID is considered by many as psuedoscience, in the same camp as creationism. Presupposing a "designer" to the universe is the old God of the Gaps mentality. I like to think that the universe evolved naturally, It is a uncaused, reality. Ironic that some theist also believe that God too is a uncaused reality. How or why does complexity nessitate a intelligent designer is impossible to answer IMO. The anthropic argument is silly and it is obvious that humans probably will always be superstitious and religious creatures. Thats one of the things that makes people so interesting I think.

Hi xevolutionist that indicates a intelligent designer, like Bees creating a hive? Oh wait are bees intelligent?
I always have been of the opinion that Shape dictates function.
Nature is the best designer in my opinion, man is always using nature as his inspiration in his designs. Can God be called Nature?
Theist choose to call the designer "God" and non theist chooses to call the designer " Nature". Are we talking about the same thing and only using a different term?
