I've answered over and over and over and over, but you aren't understanding. In the sense of teaching you something you apparently don't understand, I'll try again. And again. And again.
First, the teaching that only, solely, naturalistic mechanisms are sufficient in and of themselves, alone, without any other impetus, creates all of life, including humanity from a single life form of long long ago shouldn't be taught. No creationist viewpoint should be taught, including atheistic creationism.
Read this slowly. Move your lips if you must. Only teach evolutionary views which are scientific. Nothing else. Only scientific evolutionary views. What naturalistic mechanisms are sufficient for what? Depends on if they're scientific. If they are, teach them, if they're not, eliminate them.
