Porque esse codigo Jquery não funciona?

Front-end JavaScript
#1 
<!DOCTYPE html>
<html>
<head>
    <title>TODO supply a title</title>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <script type="text/javascript" src="aula03.js"></script>
</head>
<body>
    <div id="teste">
        <p>TODO write content</p>
    </div>
</body>
</html>

script:

$('document').ready(
    function() {
        $('*').css("color", "red");
});
#2
