Previous Entries same as Home Page

Hi, I have a problem with Previous Entries (/page/2/) displaying the same entries as those on my Home Page.

I think the problem comes from the Loop. Here is my code if that can help:

<?php get_header(); ?>
<?php get_sidebar(); ?>

<?php
        $posts = get_posts('numberposts=5');
        foreach ($posts as $post) :
?>
<a href="<?php the_permalink(); ?>" title="<?php the_title() ?>"><?php the_title() ?></a></li><br />
<?php the_category(', ') ?>

<?php
endforeach;
?>

<br />

<?php if (have_posts()) : ?>

		<?php while (have_posts()) : the_post(); ?>

<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a><br />
<?php the_time('F jS, Y') ?> | Posted in <?php the_category(', ') ?><br />
<?php comments_popup_link('Leave a comment »', '1 comment »', '% comments »'); ?>

<?php the_content('Read the rest of this entry &raquo;'); ?>

<?php endwhile; ?>

<div class="alignleft"><?php next_posts_link('&laquo; Previous Entries') ?></div>
<div class="alignright"><?php previous_posts_link('Next Entries &raquo;') ?></div>

<?php else : ?>

<h2>Not Found</h2>
Sorry, but you are looking for something that isn't here.

<?php include (TEMPLATEPATH . "/searchform.php"); ?>

<?php endif; ?>

<?php get_footer(); ?>

Thanks a lot for your help!
