Believing in science is antithetical to the scientific method. You're meant to question things and have an open mind towards the possibility of things that haven't been discovered before. New evidence could change a theory or even completely disprove it. Or require new theories to explain it.

Atheists with their "pink unicorn" dogma have a mindset that runs counter to scientific discovery. This isn't unusual among religious people, but most religious people understand that they're making arguments on religious grounds. Atheists claim their warped view of science is science.

Also there's a difference between understanding how the world works (science) and thinking about why we exist. These are orthogonal questions which may intersect at times but are more often completely different line of thinking. But the atheist perversion of science attempts to alter theories to answer the "why" kind of questions which calcifies theories into dogma, which is bad for science. And there's a tendency among atheists to push science as anti-religion which only results in religious people becoming resistant to learning science.
