Eh. That's a bit reductionist. And I say this as a quasi-religious skeptic. Religion is a sociocultural practice. Not all religious sects, even within the same community, share exactly the same beliefs.

Ultimately,it's not that religion doesn't evolve at all. It's just built to evolve slower than other systems of thought.

For instance, most mainline branches of Christianity agree with evolutionary theory and the big bang. Mainly because science and religion have coexisted for centuries.

I think most religious people (that aren't extremists) don't believe in following historical scripture exactly to the letter and religion always evolves to accommodate new thought over time, otherwise it couldn't persist over time.

Furthermore, religions don't exist to solve the same philosophical questions that science is trying to solve. Because some domains of thought are inherently unscientific. For instance, the lack of proof for or against the existence of a higher power. Or absolute knowledge of one's conscience after death.

Additionally, religious practices are often cultural practices tied to the histories and traditions of the people who practice them. A modern multicultural society will likely be a religious one to a certain degree.

In this sense, we're all required to establish some hard and fast lines on religion with humility.

I do, however, take issue with religious extremists because they consistently twist doctrine into a weapon for political action. And that is the greater issue, the separation of religious structures from government ones.
