I do not reject it. Much evidence supports it, so it'd be kinda strange to do so.
I don't reject the possibility of a creator, either. No evidence for that, really, but if such an entity exists it could as easily hide such evidence as it could create it.
I've occasionally thought that there's no real conflict between the two explanations, except what people make up because they want to disagree with one or the other.
Sometimes I think we're alone. Sometimes I think we're not. In either case, the thought is staggering. ~ R. Buckminster Fuller
