This is to all atheists: What would you say if a church person said do you have a church home?

For example, if you were going into Wal-Mart or leaving out of Wal-Mart, and a church person who is either Christian, Baptist, or Jehovah's Witnesses, who was handing out biblical pamphlets, and the person happens to stop you and say, do you have a church home? What would you tell or say to that person?
