Can atheists live without mentioning god, religion and the likes?

There is an old adage, even though it doesn’t make any sense, which says: “Use elephant bones to break elephant bones!”
Clearly, some claim that you need religion to disprove religion.
But, I understand that you can debunk religion by using logic rather than the bible.
