Going back to listing the facts of evolution.<quoted text>1) Biota on this planet changes over time. This is an indisputable fact. We refer to this change as "biological evolution."
2) Our best current understanding of the mechanics that drive this change is called the "theory of biological evolution". Any explanation that allows us to model the mechanics of this change will be called the "theory of biological evolution".
3) This understanding is ALWAYS up for revision should a better model come along. However, such a better model would have to provide more accurate TESTABLE predictive capability than our current model or else it is worthless and we are better off keeping our current model.
