Creationists seem to view scientific findings in the same way they view religious teaching. As if all the answer comes complete and defined with nothing more to know. This, no doubt, arises from a demand of literalism as the only means to interpret scripture.If the theory of evolution predicted no gaps that would be evidence against the theory of evolution. But even Darwin recognized and predicted gaps. He also predicted that as exploration went on many of those g aps would be filled and he recognized that as a possible test of his theory. Each new fossil find could be a huge problem for the theory, if it was wrong. Yet for some strange reason that creationists have not figured out yet all of these millions of fossils support the theory of evolution.
Scientific findings do not develop as complete knowledge and each finding requires effort to understand. One has to know basic principles and be versed in prior work. As well as having an understanding of methodology. It is not an exclusive club, but it does require more than simple, comfortable effort to understand. Claims have to be supported with evidence explained in a logical basis.
I know you know this, but it bears pointing out these basic points.
