Some whould argue that first life was as complicated as a 747. I think that's what the argument is.

Even if that were true, the fact is that 747s do not make imperfect copies of themselves (or copies of themselves at all) and life forms do. That is the fundamental flaw of the analogy, and that is why only the ignorant repeat it as though it has meaning.

The analogy also fails in that it implies that life formed via processes that were random and that these random events had to occur simultaneously. For a better analogy, imagine all the parts of a 747 in a junkyard. A windstorm comes through and blows all these parts around and two parts come together in a way needed for a 747. Then another storm comes and joins a third part to the first two, etc., etc...

Come to thnk of it, if we ever do design and build something that can make copies if itself with variations, it will evolve.

Selection works even on designed things.
