Like what? What would you have done better?
Designed a lower back and a knee joint that are meant for a two-legged critter, rather than relying on slightly-modified ones for four-legged creatures.
The flaws in our anatomy are pretty good evidence that we evolved, and were not created. Despite their flaws, they're good enough, which is what evolution really is- not survivial of the fittest, objectively-speaking, but the survival of the better-than-all-the-rest. If we were designed this way, the designer must have missed some pretty obvious flaws that any competent engineer could fix.
