Generaly, highly complex, interdependent, functional machinery with instructional coding and regulatory meta-code doesn't come into existence via artistic free-wheeling; it must be deliberately planned for in advance by a highly skilled engineer. The engineer might be artistic too, and might use creativity to overcome unforseen challenges, but without a planned design goal any engineer and software programmer will tell you that a functioning computer just cannot be built.
Its this kind of statement that led my comment on biological complexity. There is, I repeat, a
vast literature that deals with the issue of how highly interdependent functional biological systems come into existence without being designed. It all makes perfect sense without the need for a supernatural designer.
The Post # 56 Challenge
As I understand it, the question is this:
I arrive on an alien planet and discover an artifact. I want to know how the artifact originated, and there are 2 possible explanations: either it evolved, or it is the product of conscious design. How can I determine which hypothesis is correct?
Well, my first step is to closely examine how the artifact works. Is it an organism? In other words, is the artifact:
a) homeostatic
b) able to physiologically adapt to perturbation
c) able to recursively re-create a boundary around itself (some sort of membrane)
and
d) able to reproduce, either by itself or in conjunction with another, similar artifact? Note that this condition implies some sort of mechanism for ensuring accurate replication, analogous to our DNA.
If not, then there would be a very strong implication that the artifact was designed- simply because there wouldn't be any apparent way that it could have evolved.
If the artifact
was an organism, then my next step would be to examine the environment. Are there any other organisms with the same biochemistry extant? Are there any fossils?
If not, then I would remain unsure about the artifact/ organism. It
might have evolved elsewhere, and ended up where I found it. Or it
might be a product of bioengineering. I simply wouldn't know, and I'd have to reserve judgement.
On the other hand, if the environment did have lots of orther organisms with similar biochemistry, and there were also lots of fossil organisms, many of which appeared to be related to the organisms that were around me, I would conclude that the best explanation for the artifact/ organism was evolution.
And thats all science is, really- inference to the best explanation.
