Actually the results from long term adaptive experiments are in line with Creationism and actually also go against Darwinian evolution. The ability for created systems to adapt isn't a refutation and your car can adapt through mechanisms for turning on/off its lights. This has nothing to do with car to airplane phenomena though.
Adaption is different to evolution over generations.
If an alien landed and walked up to us we would not know if it was a designed thing or a product of evolvolution.
If it was made of flesh bone and blood we would still not know.
If it reproduced by it's self it or by sexual methods it would by subject to the selective pressures of it's enviroment and thus subject to evolution. But we would still not be able to say that it was or was not the porducet of design.
If we examined it's equivalent of DNA, that is it's mechanisim for passing on it's pattern to the next generation, we would find either of 2 things.
1 A set of instructions laid out with at least some level of intelegence and consistencey. Single ideas would have single locations. They would not be fragmented and randomly spaced out. Visualise a filing system of some sort.
or
2 An example of the selective choosing from randomness. If you visualise a hundred filing systems thrown up in the air, mixed and then shreaded, you have something of the picture of the information in DNA. Chance botch job repairs to bits that did not work are all over the place and have been refined to work well.
If you you found 1 it's been designed by an intelegent designer.
If you found 2 it has almost certainly been subject to selective breeding. This may have been overseen by intelegence and may have been added to by bits of design, genetic engineering.
If you then compaired it's DNA or equivalent pattern copying mechanisim to other members of it's species you would, if it's natural selection at work, see various givaway things going on which will confirm it.
If you are able to look at it's home planet and the other animals on there they will, if they and it have come about via evolution, show common features. Such as the general type of eye is common to all vertibates on earth. Or that the specific way blood clots involves 5 protiens when it could use 1 but this is common to us all. Then you have proof undeniable.
If you examine the fossil record on the planet and found the fossils of previous ancestor species of the alien with examples of the extinction of different "failed" branches in the time line you have proof beyond utterly undeniable proof.
If your study of some of the aniamls of the alien world allows you to make very good predictions about the way the "DNA" of the other animals is put together you have a useful aspect of the already confirmed theory.
This study of "DNA" will also allow you to make statements about when different types of animal last had a common ancester. When this reflects the way the continental plates have moved around on the planet you can afford a smug grin.
The theory of designed creation is proovably wrong (easily).
The theory of evolution is proovably correct. In sooooo many ways.
