I think there is another point to be made that I don’t think anyone has brought up.
If you think some supernatural being designed us, you have to accept that he was a really poor architect.
What kind of idiot uses the same hole to breathe, eat and drink, and speak through? This is asking for trouble. An efficient designer would ensure that the possibility of choking was not there. Humans cannot drink and breathe at the same time, but other animals can. Poor design.
Our eyes; very often cited by creationists as a good example of god’s work. But for starts they are wired upside down, er why exactly? They are also not nearly as good as a Hawk’s eyes and even a horse has better acuity for most of its visual range. We have a blind spot; cephalopods don’t!
And you know what, tropical fish and birds have tetrachromatic vision; they have better colour vision than we do (they see colour in four dimensions). Actually though this is nothing, because a species of shrimp has the most complex colour vision in all nature, it can even see circularly polarized light! Nice.
Even worse with eyes we have retinal arteries that can cause blindness.
We cannot smell as well as dogs!
We cannot hear as well as bats.
Our hips and knees, although enabling us to walk upright are very poorly designed for the job. This is why hip and knee problems are so common; a competent designer would have made a much better system. Also because of our upright gait, the female pelvis is not really wide enough for a baby’s head. Which leads to death and injuries. Bummer.
You know what, we age really badly, why couldn’t our skeletons and skin and organs have been made from more durable stuff? We as mere humans can create much longer lasting objects.
Congenital defects; in the womb we almost retrace evolution and go through a stage where our little embryos have gills; these are sometimes left over at birth.
There are many other flaws but I think you get the point; if something did design us, then it was a fucking idiot and just about any educated human could do a better job.
However, all these flaws make sense in the explanatory light of evolution; evolution shows us our past through these flaws, and also helps us to combat them and improve the quality of human life.
