I have met and known many atheists, though obviously not all or even most of them.
However, I have never heard any atheist calling their place(s) of meeting a "church".
Nor have I ever heard an atheist call their belief system a religion.
But, again, I don't know all atheists... just a few.

Atheists Are Sometimes More Religious Than Christians
A new study shows how poorly we understand the beliefs of people who identify as atheist, agnostic, or nothing in particular.
Americans are deeply religious people—and atheists are no exception. Western Europeans are deeply secular people—and Christians are no exception.
These twin statements are generalizations, but they capture the essence of a fascinating finding in a new study about Christian identity in Western Europe. By surveying almost 25,000 people in 15 countries in the region, and comparing the results with data previously gathered in the U.S., the Pew Research Center discovered three things.
First, researchers confirmed the widely known fact that, overall, Americans are much more religious than Western Europeans. They gauged religious commitment using standard questions, including “Do you believe in God with absolute certainty?” and “Do you pray daily?”
Second, the researchers found that American “nones”—those who identify as atheist, agnostic, or nothing in particular—are more religious than European nones. The notion that religiously unaffiliated people can be religious at all may seem contradictory, but if you disaffiliate from organized religion it does not necessarily mean you’ve sworn off belief in God, say, or prayer.
The third finding reported in the study is by far the most striking. As it turns out, “American ‘nones’ are as religious as—or even more religious than—Christians in several European countries, including France, Germany, and the U.K.”
“That was a surprise,” Neha Sahgal, the lead researcher on the study, told me. “That’s the comparison that’s fascinating to me.” She highlighted the fact that whereas only 23 percent of European Christians say they believe in God with absolute certainty, 27 percent of American nones say this.
America is a country so suffused with faith that religious attributes abound even among the secular. Consider the rise of “atheist churches,” which cater to Americans who have lost faith in supernatural deities but still crave community, enjoy singing with others, and want to think deeply about morality. It’s religion, minus all the God stuff. This is a phenomenon spreading across the country, from the Seattle Atheist Church to the North Texas Church of Freethought. The Oasis Network, which brings together non-believers to sing and learn every Sunday morning, has affiliates in nine U.S. cities.
Last month, almost 1,000 people streamed into a [Atheist] church in San Francisco for an unprecedented event billed as “Beyoncé Mass.” Most were people of color and members of the LGBTQ community. Many were secular. They used Queen Bey’s songs, which are replete with religious symbolism, as the basis for a communal celebration—one that had all the trappings of a religious service. That seemed completely fitting to some, including one reverend who said, “Beyoncé is a better theologian than many of the pastors and priests in our church today.”
Definitions are going stupid and that is why I wrote ----
Since following an ideology is a prerequisite of religion, atheism can be considered a religion, since atheists draws on philosophical ideologies to guide ideas, behaviors, and actions, like that of any religion. That is why atheist churches are called atheist churches.
