Here is a link to a story about "Thirty-eight Nobel Prize laureates asked state educators to reject proposed science standards that treat evolution as a seriously questionable theory, calling it instead the "indispensable" foundation of biology."

I think that the important point is that this is how the science of biology is developing at present and it's the key concept holding it together. When and if it fails observation and experiment than new theories will be developed. The religiously motivated theories aren't being advanced to meet scientific needs.
I agree with your viewpoint as I understand it.
