Evolutionary Science was wrong? How can this be?

Evolution is a fluid, unstable theory. That is, it changes. What evolution stated as scientific fact ten years ago is, today, a verified fallacy. And the “observable, provable scientific facts” of today may be dismissed during the next decade. The science upon which atheism is anchored is floating. And if the fact of today is the fallacy of tomorrow, then in reality, it is no fact at all. It is upon that anchorless rhetoric that atheists build their claim of reason.
