tough questions from kids - why should we go to God for help?

Asking why we should go to God for help is like asking, "why should I go to the gas station for gas?" we need God because He is the one who gives us life, for one who makes us able to walk; talk and move. He is the one who gives us knowledge and the one who give us all we need. In a sense, God is the only one who can help us.
