You're not understanding my point. The scientific evidence is that birds are descended from dinosaurs. Scientific evidence can't make birds be dinosaurs, because it's up to us to define "bird" and "dinosaur", and we can define "bird" to exclude dinosaur (and I think most people still do). Just like we can define "fish" and "human", and we can define "fish" to exclude human, even though some fish learned how to walk on land and one of their grandkids is typing this comment right now. Biologists might wish that we all adopt cladistic definitions for types of organisms, but that doesn't the world will follow.
