A Round Earth, Natural Selection, and Dinosaurs

What do a round Earth, natural selection, and dinosaurs have in common? They are all things that are demonstrably true and biblical that some professing Christians deny. All of these things are mentioned or implied in Scripture. And they are scientifically provable. Yet, some Christians claim that such things are false or even anti-biblical! When Christians deny things that are observable, provable, and biblical, it is dishonoring to the Lord and makes unbelievers less likely to embrace the Christian worldview.
