Yes, I understand all this.
A theory is an explanatory framework for observed phenomena.
The theory of evolution is one of the strongest theories we have in science.
Yet even its defenders admit that it is problematic, and so have come up with such stopgap revisions as punctuated equilibrium.
That Evolution is "problematic" doesn't mean that it isn't the best description of the observed phenomena. It will not be discredited unless serious quantities of new information are found. Something even the efforts of "Creation Scientists" have not been able to do to any extent.
