Religion at its best is not a collection of superstitions and rituals, it's a very positive philosophy and set of ethics. Religion also does not necessarily require you to believe in "a creator". Some types of religion do require that, but not all types by any means.

Religion is often entirely compatible with science...but goes into further areas which science is not inclined to even comment upon...those areas having to do mostly with philosophical and ethical viewpoints on life and inquiries into the meaning of life.

That is to say, science is primarily concerned with the objective, while religion is primarily concerned with the subjective. Since a person needs to understand and experience both objectivity and subjectivity to be a complete personality, it would seem wise to look at the world through both viewpoints, and in a way that can harmonize them.
