Then again, God specifically gave people the province to eat meat after the Flood.
I tended to just read that as more of analogy -- right now, all we know is this world where the strong prey on the weak and the system dominates, but at some point God will set things right and fix them so that the normal predators and prey will be able to coinhabit and not need to attack each other and thus live in peace. Israel back at that time was never really much at peace, there always seemed to be some threat or another... or drama within the nation itself.I recently noticed in Isaiah it says something like, "On My holy mountain, the lion will graze like the ox" (perhaps another grazing animal). That does leave a problem of when and why the world went off track when it comes to how God would be running things. I don't know how to answer that.
I think science was different then. It was far more outside the box, and you were fighting the establishment. It also took a dedication/commitment, spending your life pursuing something other than a viable trade. Lots of gray area to explore too, whereas nowadays there's a lot of science that is more procedural and implementational.
Also, "Christian" might be applied loosely. There might be Deists in there, for example, which aren't considered Christians by some conservatives nowadays.
I think one thing driving much of early science is that it helped to believe that the world made sense in some way -- and the idea that a God made everything to work a certain way provided impetus for them to have faith that, if they explored it, they would find something rational underpinning it.
