This isn’t good, but not for the reasons you imply. As an atheist, I do not ‘believe’ in evolution. I accept that, given our current state of knowledge and the evidence we have, the theory of evolution is the likeliest explanation for biodiversity. This is not something which requires belief, because it is evidence-based, and because it is subject to change as and when new evidence and knowledge emerges. Belief is independent of evidence, being merely a strongly-held opinion.

Believing in evolution is every bit as bad as believing in God. We must learn, all of us, to critically examine evidence, accept explanations that arise from said evidence, and above all, be prepared to change our views if and when other and better evidence emerges.
