You should note that evolutionary biology has an explanation for the various oddities of "design" that are being discussed. You should then note that when you make up explanations they run into problems immediately.
I think you can pass judgment either way if your level of knowledge isn't up to the level needed to give the subject matter a fair judgment. It depends on how you wish to look at it either way based on whether you are an atheist or a theist. I believe this is rational but, it is a road many people don't wish to travel on.
The acceptance of the evidence and logic of evolutionary biology is not split by whether one is an atheist or a theist. Only a small minority of theists don't accept that the explanations of biology are reasonable and very probably correct. E.g. Our eyes.
You may say that you can look at it either way. But using your way you end up in a tangle that doesn't explain the available facts. Therefore one way is deficient in the extreme.
