Not directly, but people find ways to believe in a manner analogous to religious beliefs. Faith doesn't have to be directed only at traditional theist objects. Religious or not, people can believe things by faith and by logic.
To give an example, science is not a replacement for philosophy, nor is it implemented perfectly, but some people elevate it far beyond its means to answer certain inquiries. That is irrationality, or faith.
> science is not a replacement for philosophy, nor is it implemented perfectly,
Yes, but it is far better than a fraud. Therefore it is the best we have to understand the world. And fairy tales invented by illiterate people thousands of years ago aren't a path to understand the world. They're a fraud, plain and simple.
I think you're being uncharitable towards religion. While I agree that a belief such as "the Earth was made 6000 years ago" is ridiculous, a belief like "God wants us to love our neighbors" is not. I think "good beliefs" (a very loaded term, mind you) get rediscovered constantly, in religious and nonreligious contexts alike. These are beliefs attained through philosophical inquiry. The beliefs provided by science are complementary.
> I think you're being uncharitable towards religion.
You are correct. I am, deliberately, "being uncharitable towards religion". I had far too much Catholicism in my upbringing to be respectful of any religion. If you want to know what I mean by Catholicism read the story linked by the title post, about Catholic parents in Catholic Spain. My story wasn't that bad but I saw a lot of that prejudice, arrogance and intolerance. It isn't surprising that in 50 years the country of Spain went from majorly Catholic to majorly agnostic.
> a belief like "God wants us to love our neighbors" is not.
You don't need "God wants" in that. Empathy doesn't need "God". Unlike what church people think, non-religious people have empathy and decency, too. Human beings are social animals, doing empathy is a common trait that doesn't need "divine" justification.
I agree that religion isn't necessary, but it's not necessarily bad. You're making a big generalization. There are plenty of people who abuse religious beliefs, but I'm more concerned with calling out people who abuse principles from any cut of cloth, and religion is only a part of that.
