Human evolution Intelligent Design theism

Asked of Steve Meyer: If humans are so important to God, why did they take so long to develop?

In the book, Meyer argues from three scientific discoveries to an inference to a personal God. If God is the creator, Keating wants to know, why was He so patient as to wait billions of years, during which not much that was very interesting happened, for the fulfillment of His purpose in initiating the universe to begin with?
