This stemmed from the monotheistic principles and is in no way an obvious assumption (consider the Greeks).
This is nonsense. Of course it's obvious;
nobody acts like things happen in a vacuum. In fact the hardest thing for human beings to do is accept that two promixmal occurrences are
unrelated. We see patterns
everywhere; it's not unique to science or religion, it's just what people do. It's how gods get invented, in fact.
I mean, why would an intelligence evolve that couldn't perceive how things were related? How would intelligence even be possible otherwise?
This principle is purely a religious one
You're just assuming your conclusion - circular reasoning. We could just easily say that the principle is purely
scientific. Or that it's neither religious nor scientific, but epistemological.
