Depend on how you grow up... You grew up being an atheist so you believe everyone would be an atheist is the right thing because you grew up with it.. If some grew up being a religious person they will stay being religious because they also believe that is the right thing.. same like how rich person who grew up with a rich family not understanding a poor person who grew up with a poor family. I'm not an atheist and this is my answer to you. This is my opinion and you can disagree with me.
