Is religious belief really that important?

When people are confused about many problems that science can't solve, it's easy to think that there is some mysterious force dominating everything in the world, so they choose to believe this mysterious thing. People who believe in science or religion regard it as their own belief. From this perspective, people need faith and spiritual sustenance. Therefore, it is really important for people who choose religious beliefs. Every religion has a doctrine of being kind to others, and even has a certain universal spirit, which has a positive effect on the harmonious development of society. Of course, it is sometimes used by some people with ulterior motives, which will cause great social unrest and anxiety, which also reflects the great influence of religion.
