Good scientific approaches should converge on the truth. In secular origin-of-life studies, theories run off in all directions, often crashing into one another.
The history of the world and its life could hardly be more different between the Bible's account and that of modern evolutionary naturalism. Some recent scientific reports fit with a designed, recent creation, and do not fit with evolution.
