Thousands of atheists turned out Saturday (June 4) took part in "Reason Rally" at the National Mall in Washington.
Atheists, agnostics, and freethinkers came to hear speakers talking about the importance of keeping church and state separate.
They want reason and science and not religious beliefs to decide politics and public policy.
Out of all the members of Congress, only one member, Rep. Kyrsten Sinema (D-Ariz.) — says she's religiously unaffiliated.
More than 90 percent of Congress calls themselves Christian.
But nearly 1/4 of Americans say they don't have a religion and many of those just don’t believe in God.
So, the Reason Rally is a way to show some muscle and demonstrate to lawmakers that the non religious community just happens to be people who vote.
