Rename index.php to index2.php now e dont have a index :) so we create a new file called index.php and put in there
<?php
if(isset($_GET['page'])) {
$page = $_GET['page'];
if($page == "news") { require('news.php'); }
else {
require('index2.php');
}
?>

That will now give us index.php?page=news which will be the same as news.php
