Sure if no Creator to the universe, the universe doesn't have a purpose. But if an Atheist chooses the reason why they want to live, then that is a purpose of living and especially if it's a good reason. The same is true of why one wants to do good.
Perhaps the purpose of an Atheist to live is simple: "he finds life worth living".
Also, it could be that their parents wanted them to live a good life. So they have a purpose in the eyes of their parents.
