If god created us why is the human body so poorly designed?
There are literally thousands of things that could go wrong at any time. Our Knee and shoulder joints are just awfully designed as is our spines. The human skin is incredibly susceptible to thousands of diseases, rashes and problems. Virtually every human at one point experience some kind of dermal problems, be it rash eczema or fungal growth. The only thing amazing about our bodies is our brains and it too has a host of diseases and is susceptible to dangerous mental problems. Cancer is all but assured given a long enough time frame. From a design standpoint there is something wrong or imperfect with virtually every part of our bodies.
If it wasn't for modern medicine i doubt most of us would live even to our 50's.
