Because he didn't have any.
He didn't have the skill to remove our useless organs like the appendix. He didn't give us the ability to produce vitamin C from food, even though we need it. He made us dependent on direct sunlight for vitamin D to function properly, even though in most of the world doesn't have enough exposure year round.
He gave us extra teeth, which wouldn't come in till later and would most likely KILL us when they grow in crooked and sideways before the days of dentistry. Actually in the days before dentistry our teeth were the cause of many deaths.
No, he was more concerned with being obeyed and "loved."
