Some scientists suggest so. Before I can decide, I have a couple of questions: 1. What do they mean by science? and 2. What do they mean by religion?
Scientism dominates belief about reality these days. It's the idea that what is real is what can be studied by science. Science is universally applicable to every kind of knowledge pursuit. Empirical study is the most reliable kind of knowledge. That's pretty much how people approach things these days. The man the lab coat is the authority on every kind of subject.
But science can only study things that fall within its domain and methodology. And since naturalism dominates science these days, for science to study religion, religion has to be reduced to a purely natural phenomenon. Religion becomes behaviors, brain chemistry, etc. That's not religion. While science may be able to study certain aspects of religious phenomena, science just can't study religion. It falls outside its territory. But that's not surprising. Lots of important things do: morality, values, logic, consciousness, theology, etc.
If science cannot study religion because it doesn't have the resources to do it without fist reducing it to something else, that doesn't mean religion isn't part of the real world where facts and truth guide us to discover reality. It simply means it's another area of study. So I'm guessing I'll answer this question "no." We should use another area of knowledge to study religion.
