Why does it seem that many people who cannot get into the spirit of questions about God and answer on the belief He exist?

Someone ask a question about God, but rather than answer in the spirit of the question as if God exist, others will answer to either state that they don’t believe, therefore, they either won’t answer, or they go off context and question what is God, or whose god, etc. Why can’t those people stay on point and answer question about God in context, and in the spirit of the question?
