Well, although I do prefer evolution to a story about intelligent design myself, the former is not exactly watertight. For example - it relies too often on the advanced elements of the chain self evolving on demand to "tech" it couldn't possibly self invent. Some sharks, for example, evolved from proto sharkie at some point, not much brain on that fish, but it managed to self develop fast "nose". Ocean was vast, there wasn't enough food, it had to be fast, so it evolved its body. That's fine, happens all the time in nature apparently.
However, soon enough after the nose grew, it turned out, sharkie (a specific kind, swordfish protoplast) made a bit of an error and overdid focusing on the whole "speed" issue as all of the streamlining of the frontal details had a bit of a side effect in its natural habitat - the fishy suffered from frosty vision and brain freeze in cold waters when moving so fast.
So instead of spending next few thousand years widening its head, or becoming slow moving vegetarian, the shark/swordfish protofish managed to wish special tech into life - heated windscreen. It wanted to see well so badly, that at some point one of the muscles that moves its eyes started produce heat by warming up the blood that flows through it and diverting it towards the eye and the brain. It kept on tweaking it until it reached optimal value of 15 degrees celcius above the rest of the head.
Now, you see, it could have gone about it so many different ways. Develop new organ, or change shape, like before. It didn't improve overall blood circulation, or move to warmer waters, close to the surface. It didn't develop special scale, or eyelid, or extra layer of fat under the skin. It literally just modded existing part to a new thing. No other ocean animal had it, the proto shark-o-swordfish couldn't see it anywhere else, so it just simply flipping hotrodded the tech out of nowhere. And then spent the next gazillion years being just as stupid and "unevolved" as before.
And that's all right. It doesn't surprise us. We have parts inside of our own body, that we are not 100% certain of what they do and what exactly they control in the complicated system, we couldn't observe them at work in other animals, without biolabs, gene mappings and microscopes but we are fine with the notion that our ancestors felt so much unexplained need for them, that at some point, the code carried between generations just opened another tab, started another branch of development and eventually after some time we grew a specific part inside of us. Usually one we didn't know even existed up until some 20-30 years ago and we had to spend few decades to reverse backtrack what it actually produces for what else to work. But we want it to be our decision. Like losing monkey tail or re-encoding ourselves to keep hair in most unwanted places of our body for no other reason but to stink, while in the same time, involuntarily losing hair where we would actually prefer to have it always. Evolution, in those cases, just feels like a better explanation than someone screwing around with the code every few million years to change or improve it. And all of that, mostly, because believing otherwise, would involve some magical Jew or old bearded man stretching his index finger in act of creation, or worse yet - a flipping Erich Von Daeniken telling you porkies about ancient space pilots landing in Nazca.
