Still don't understand your point. Sorry.
My point is: Darwin himself did not state that his theory was based on firm facts, and that someone else could look at the same evidence and come to other conclusions.
Followers of Darwin have taken his "speculations" and expanded them far beyond what he himself stated.
It is OK to follow a different religion, just don't call it proven science.
His theory of incremental change over long time is refuted by the fossil record. It hasn't been shown how the changes took place. It is still an open question that is disputed by the Religeonists of Darwin.
