One can say that religion is more of an art than a science.
A science implies definite and absolute answers. Evidence based, "the facts," objectivity. Art is more about freer thinking and creativity, personal experience, intuition.
When we look deeper, tho, science isn't all rigid either. There's relativity theory that we are still struggling to wrap our minds around. The truth of things like distance and time being relative to the observer. Then there's also the quantum realm. A realm where something can be in more than one place simultaneously. Multiple truths at once. Fuzzy logic.
At the level of everyday life, there are many seemingly rigid scientific facts and truths. We base a lot of our technology on these truths; like assuming electricity behaves in a certain way. This isn't the "be all and the end all of science," but it works to keep the lights on and to keep our lives running.
On the other hand, there are many things that science doesn't answer. It doesn't answer these things yet at least; if it ever will. Questions like, what started the universe, if there was a start. Is there a larger meaning to our lives? Seems like these questions lead to the fuzzier, quantum side of science. There's lots of room for creative thinking. Religion deals with these questions also.
Seems like we get into trouble when we try and put these unanswered questions into the realm of rigid, absolute fact; especially when we don't have definite answers. It just causes us to start fighting among ourselves.
