There are many ways people can believe there’s a god like evidence or faith or religion you followed your whole life. Like Christians putting their life in Christ or Muslims I haven’t studied about them, but I know some and there’s Agnostics which are people that knows there is a god but not knowing how or what he or she is like me I’m Agnostic. There’s also Atheists which believe no god is real and there are many religions through parts of the world. For example, India, America, or Israel many different what ifs and other people believe different things it’s your choice on what you are in your mind if you go to church every week or not if you pray or not.
