Think about as science asking what can I understand about the {life, the universe and everything} that doesn’t require a supernatural explanation? Think about {religion\philosophy} as asking what can I understand about the {life, the universe and everything} that requires a supernatural explanation? With this viewpoint you can see that they are not necessarily in conflict but can actually be complementary.
How about:
Think about science as asking:
"What can I understand and the universe that I can attempt to avoid human mistakes and biases from coloring?
This requires ('cause I can't think of another way) that I have something that independent observers can check, test etc. separately from me and my biases. That leaves out a lot of thing including the supernatural.
