If a pilot crashes a jet plane and then the plane is damaged, that doesn't prove that the jet plane wasn't amazingly designed.
human body that you say was created by the infallible god vs a jet designed by fallible humans isn't really an apt comparison.
some flaws of the body i am referring to: our use of the pharynx for both ingesting as well respiration. this can and has led to choking if we aren't careful.
extremely narrow birth canals on women, leading to tremendous pain. previously a leading cause of death for women was giving birth, improvements in medicine fixed this.
the blind spot in our vision (https://en.wikipedia.org/wiki/Blind_spot_%28vision%29)
so you probably want to be careful with this argument, you are indeed unwittingly claiming god is fallible when linking the greatness of god with the human body, that is far from the perfect machine you believe.
