people can make a legitimate case that evolution in the sense of macroevolution has not been demonstrated as proven (to 100% certainty) - Del.JW
You are equivocating about the meaning of the word 'proof'.
It strictly belongs only to the realm of mathematics where it basically involves showing that a statement is a tautology. In every other field of knowledge we assess the balance of evidence. The fact that every living thing descended from a common ancestor over millions of years is as absolutely certain as the fact that the planet earth is not flat.
If you want to argue that this is not '100% proven' then carry on but how does it add anything useful? SBF and others hide behind it to pretend that anything is equally likely.
