One of the objections to evolution that creationists tend to use is that they believe that all the complexity of life could not have come about through purely random means - it's too improbable. They're right that it's hard to believe. It's a good thing, then, that this is not what evolution says.
Evolution is not a purely random process. One of the mechanisms (there are others) that allow for change to occur is random mutation, which is a random process. These mutations are impossible to predict and allow for small differences in off-spring that may or may not provide an advantage in survival and reproduction. This is done through natural selection, which is not a random process. By ignoring the non-random selective process, creationists and anti-evolutionists effectively create a straw man of an argument that does not represent what evolution actually says.
