wp_insert_post as page not working?!

Ok so I have a plugin that I would like to have automatically create a page on activation, but every piece of code I have tried has yet to work. Every once in a while, it will decide to add the page, but I can never get it to repeat itself. (deleting page, deactivating, then reactivating plugin to test)

Here are the scenerios I have tried.

<?php
wp_insert_post( $new_page );

$new_page = array(
'post_title' => 'Employees',
'post_name' => 'employees',
'post_status' => 'publish',
'post_type' => 'page',
'post_author' => $user_ID,
'post_parent' => 0,
'menu_order' => 0
);

	//if we have created any new pages, then flush...
	if ( $newpages ) {
		wp_cache_delete( 'all_page_ids', 'pages' );
		$wp_rewrite->flush_rules();
	}
  ?>

<?php
if ($_GET['activated']){

    $new_page_title = 'This is the page title';
    $new_page_content = 'This is the page content';
    $new_page_template = ''; //ex. template-custom.php. Leave blank if you don't want a custom page template.

    //don't change the code bellow, unless you know what you're doing

    $page_check = get_page_by_title($new_page_title);
    $new_page = array(
        'post_type' => 'page',
        'post_title' => $new_page_title,
        'post_content' => $new_page_content,
        'post_status' => 'publish',
        'post_author' => 1,
    );
    if(!isset($page_check->ID)){
        $new_page_id = wp_insert_post($new_page);
        if(isset($new_page_template)){
            update_post_meta($new_page_id, '_wp_page_template', $new_page_template);
        }
    }

}
?>

And the one wordpress has posted in the codex:

<?php
// Create post object
  $my_post = array(
     'post_title' => 'My post',
     'post_content' => 'This is my post.',
     'post_status' => 'publish',
     'post_author' => 1,
     'post_category' => array(8,39)
     'post_type' => 'page' /* this actually makes the entire backend to disappear so I have to put it in $defaults=array( for it to reappear. The page doesn't always want to show up though.*/
  );

// Insert the post into the database
  wp_insert_post( $my_post );
?>

With this last bit, I can get the pages to appear, but posts are also created…I don’t need them!
