You're abstracting the problem of denying the influence of how we view the world on how we view results of science, which is ironically enough a metaphysical error. It's of course better to be actively ending starvation, but that wasn't the question. The way we interpret facts determines how we go about ending starvation. Of course reality doesn't care about what we think of it, but the way we interact back with reality certainly does!
As for the question, you dodged it. The answer is that the development of history is a result in shifting material conditions, which changes how we think and reshape the world. Like it or not, religion was in fact early science. Science itself is not a philosophy, it's how we understand the world. What you are grasping at is a vulgar materialist conception of science at best, but this misses how change and development actually occur, and results in errors by abstraction.
This is the reason world outlook is important, you're assuming you already have the correct world outlook while refusing to grapple with the fact that you have one. It's SchrΓΆdinger's philosophy.
