If religion has become "a part of our brain" then so has slavery, rape and the divine right of kings, for the same reasons. Yet no one argues that we just "have to learn to live with" the latter.

It isn't evolution, at least not in any genetic sense, it's simply culture. People believe religion is an immutable fact of life and the only possible source of meaning and morality when their culture teaches them as much. But there are cultures where religion matters far less than it does in, say, the US, where people get along just fine.
