Religion is not just a temporary thing that helped us adapt to our environment. Rather it is a permanent and central aspect of the human condition. This is a bitter pill for secular, nonreligious people to swallow. Everyone wants to think that they are in the mainstream, that they are not extremists. But robust religious beliefs dominate the world. There is no reason to expect that to change.
