Because God created all things as they are. While all creation has the ability to adapt to it's surroundings, it does change form. All we have been able to observe "scientifically" is extinction of species, not evolution of species, and that is in keeping with biblical accounts.
(even the Inuit believe in the creator which created all things)
I see. So God created a dynamic, changing, adapting world. Yet the concept that He created a world that evolved based upon His laws that He created is unacceptable?
I don't see how evolution is at odds with anything but a strictly literal interpretation of the Bible. In which case the creation story is the least to be fretted over!
