Some people do. Although, I have a difficult time understanding how someone can believe in both. They completely contradict each other. In my opinion evolution is completely impossible, a big explosion could nver have created this universe. And then conveniently life started on this planet, which is also conveniently the only planet that can sustain life. And then we all came from single cells organisms...not likely. It takes way more faith to believe in evolution then it does in God/creation.
Evolution does not discuss how the universe originally came about, or how the first animal came about. All that evolution does is explain why there is such a wide diversity in animals. Many people reconcile evolution and God in that God created the universe and the first organism, and evolution explains the diversity in animal species.
As for life living on a planet that can sustain life, you could view it as life conforming to available conditions. For example, there are creatures that live deep underwater, near volcanic vents. To any other creature, the pressure would be far too high, far too hot, (hundreds of degrees), and a severe lack of sunlight for photosynthesis. Instead, they live through a cycle called chemosynthesis - consume carbon-based molecules, expel organic matter. Isn't that neat?
