I believe that Christianity can still be believed, even if Evolution is true. ~C.S.Lewis
I see no need to disbelieve evolution on the principle that it diminishes God's place in creation. The accounts of creation in Gensis leave a room for speculation: The Genesis creation is entirely Earth-centered. The Bible is not God's plan for the universe, or God's complete and total account of all of his workings everywhere; it is a very specific story of his workings on this planet, specializing in one particular group of people that live here; how he worked through them and for them; and what became of those that he directly affected while walking around for a few years on our little swirling rock. Even that account leaves gaps. Other than a few speculatory passages, there is no account of what he did with the rest of the population in the same little history. Nor what he intends to do with those that won't get a chance to hear this little history now. Since the Bible is only intended for a very specific purpose, it is the hight of ego to assume that nothing at all happened until the moment before we appear into the universe.
The following little story is the image of creation in my own head, influenced liberally by Tolkien's Silmarillion and Lewis' The Magician's Nephew. It isn't intended to be doctrinal, but a fantasy that allows for both creation and evolution. (That having been said, it doesn't matter one bit whether one believes in one or the other, so long as everyone agrees on the core beliefs. But western Christiandom specializes in majoring in the minors, and it would be good to remind ourselves from time to time that passionate fighting on the minors both detracts from our witness, and takes time and resources away from helping those we're meant to help)
God spoke, and all the matter that would become the Universe burst outward into the void. And God and the Angels watched as the matter began to form together. Some globs swirled together and burst into flame. These lighted balls began to dance through the heavens. Some bits of matter were pulled into their dance, and began revolving around the points of light. And the great Celestial dance was made, each ball of matter, large and small, taking their place. And the stars sang together while all the angels shouted for joy. A few balls of matter erupted, spewing clouds that wrapped around the bare rock, concealing the face. Plates of rock ground together. Mountains pushed up from under the surface. Lightning struck the rock and pools of mud began teeming with microscopic life. And God looked down, and caused streams of water to come up through the rock and flood the entire surface. He pooled the waters together in places. He breathed and small points pushed through the newly exposed earth, small at first, then growing larger, and spreading green branches toward the sky. In the new moisture small tufts of heath covered the bare earth. Bright points of color appeared, dotting the ground. In the waters, the microscopic life took on new shape. Large creatures, and the small ones, and ones that could not be seen. God beckoned and some swam toward the shore and changed shape. Their scales hardened. Their fins became feet and claws instead. They grew in size. Some grew strength in necks and tails and began rampaging through the foliage. Others grew stumpy and muscular. Some developed spines, and sails, and ridges. And they lumbered around the new fresh planet. God beckoned again, and more creatures emerged from the seas. These ones lost their scales and hair sprouted. Fins and flippers morphed into all kind of claw and hoof and pad. Flippers sprouted feathers and became wings. Some ran, some galloped, and a few walked upright. And God took interest in one such creature, and changed him the most of all. He drew him into a shaded glade between four rivers. He caused the animal to shed its fur, and changed its shape. Into its mind He poured parts of himself; his desires, creativity, and love of beauty. He breathed a soul into the man, and woke him.
