Science attempts to understand reality...that's not exactly it though, since there's still some overlap between the two. The infinitive verb part still needs a little work. Still, the rough groundwork gist is there.
Religion attempts to justify reality.
Q: Why do things fall down?
Dr.S: Let us work on this one and hopefully find out.
Fr.R: Because they just do?
Q: Why do bad things happen to good people?
Dr.S: Because they just do?
Fr.R: Let us work on this one and hopefully find out.
It might work better to have it be that these things "try to help folks to [whatever] reality". As in, religion tries to help folks to accept? Something along those lines. As I said, I'm still working on it. Still, it came about due to my thinking about it and realizing that there's no reason why one can't mix the two with full faith in both at the same time (I'm looking at you, Intelligent Design! Don't try to pretend you're not a religion thing!!), unlike with many religions.
