Christians, in what ways is the theory of evolution flawed and unacceptable?

Christians object to macro-evolution, not micro-evolution. We know things change. We just don't believe that one species changes into another. Isn't it funny that archaeologists and geologists the world over have had decades to search for proof of macro-evolution, but nothing has been found. It should be everywhere. On the other hand, creation is something that can be neither proved, nor disproved. While no one can come up with a decent, plausible theory to explain the origin of life, I'm sticking with creation.
