Why doesn't she tell us?

If God existed - she could tell each and every one of us personally and unambiguously. She could, but she doesn't. Instead, the people that want you to believe in God take it upon themselves to tell you that you should believe in God. Who do these people think they are? Why would we ever believe the word of someone claiming something for which, throughout all human history, and throughout all time there is not the slightest evidence?
