In that case I did not get rid of my belief in god, my belief in regards to god changed (although in fairness, I have often described it as losing my belief, but that isn't technically accurate). While atheism can be defined as a lack of belief in god/gods, I would characterize myself as believing that god does not exist. In that sense, my beliefs changed. Is it desirable? Meh, I dunno. I was not particularly thrilled to see that my belief was changing, but I was happy as a believer in god and I am happy as a not-believer in god. I just like being me, believer or not (with apologies to Ripley).
"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."
