EXACTLY!
[alloysteel]We are all basically highly complex machines, and even the most sophisticated and gifted artisans among us have yet to achieve that level of intricate and knowledgeable technology.
As Dr. Doom pointed out, think free market. If you look at the history of any modern industry or marketplace or economy, chances are nobody ever sat down & designed it. It evolved, probably haphazardly & unexpectedly, from much simpler beginnings. Yet in some ways an industry or economy is just as amazing in its complexity & efficiency & resilience (what a combination!) as the very best designed individual machines, or most ordinary living organisms.
(Ironically, the only economies I know about that were explicitly designed are the Communist economies. And we know how well they turned out!)
*YAWN!* Think about it: free markets are "spontaneous" only in the sense that they have no central planner. They are however directed by numerous intelligent individuals acting by design predicated on their own self-interest.
But if you really think you can compare them to spontaneous evolution from pond scum, why go right ahead....
