It's possible that this whole question is a rusty cart which just won't go. But I thought I might bring it up anyway because many people seem to think of "artificial" as also being "un-natural", and that's an interesting error to make.
Things that are artificial, are a sub-set of things which are natural. they are NOT the OPPOSITE of things which are natural.
On some of the creation/evolution debates, some people who staunchly support the idea of a natural world, also seem to argue that things which are artificial are not natural, and that's an interesting error to make because it almost implies a third view of things: Natural, Supernatural and Artificial
(I'm still tryin to make the rusy cart go... thinking that there's a discussion in here somewhere. But I'm having trouble even convincing myself

)
