Where is God?

I read this anecdote in a German Book:

A mocker met a child. “What are you doing?” he asked. The child answered,” I am thinking about God.” The atheist took an apple out of his pocket,” I am going to give your this apple, if you tell me where God is.” The child took two apples out of his pocket, “I am going to give you these two apples, if you tell me where God not is.”

A clever child!
