Why complex form requires an Intelligent Designer

There is an infinite number of potential geometrical shapes, but that doesn't stop the guys at Oak Ridge from using genetic algorithms to produce new designs for nuclear reactors. There is an infinite number of potential computer programs, but that doesn't stop computer scientists from using genetic algorithms to produce computer programs. There is an infinite number of potential electronic circuits, but that doesn't stop engineers from using genetic algorithms to produce functional electronic circuits.This is because it is not necessary to search the entire space of possibilities to produce something that works. If it was, then evolution would be impossible --- and so would design be, for anyone not omniscient.

A load-bearing truss produced by a genetic algorithm. Just one of an infinite number of possible geometric forms. The result, a twisted, organic-looking structure that has been compared to a human leg bone, uses no more material than the standard truss design but is lightweight, strong and far superior at damping out damaging vibrations, as was confirmed by real-world tests of the final product. And yet "No intelligence made the designs. They just evolved" (Petit 1998). More here.

Actually, the Trojan War would have ended rather differently if the Greeks had used creationist tactics.Scene: outside the gates of Troy. Enter a bunch of Greeks making whinnying noises.TROJANS: What do you want, you bunch of Greeks?
GREEKS: We're not Greeks.
TROJANS: But you look like Greeks.
GREEKS: We are, in fact, a horse.
TROJANS: A what?
GREEKS: A horse. A wooden horse. With wheels. Why don't you open the gates and drag us into the city?
TROJANS: You don't look like a wooden horse.
GREEKS: No? What do we look like?
TROJANS: You look like a bunch of Greeks who've crossed out the big letter G on their shields and painted in an H.
GREEKS: Oh ... right ...
TROJANS: I see that some of you are carrying a banner saying "We Are A Large Wooden Horse".
GREEKS: Yes. It didn't convince you?
TROJANS: It lacked authenticity, put it that way.
GREEKS: We worked on it all night.
TROJANS: I'm sure you did. Nonetheless ... the end of the Illiad's going to be a big let-down, isn't it?
