I'm not sure what you mean by "get rid of belief." Our beliefs can change; they probably do all the time as we learn more about whatever it is we express a belief in. I only desire to 'get rid of' beliefs that are not true, and come to believe things that are. But we're not really the most rational of creatures thanks to a brain that remains in a state better suited to whatever it was we were doing before we ditched hunter-gatherer societies for farming and city-building.
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
