Posts not showing up

Hello dears,

I have put the loop, the page content is displaying but not the posts, this is my code:

<?php

get_header(); ?>

	<!-- site-content -->
	<div id="primary" class="content-area">

		<!-- 01/11/15 Adding div for the content of the page -->
		<div class="2colums-presentation">

			<!-- 01/11/15 creating column to put content on the left -->
			<div class="column1">

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

						<h2><?php the_title(); ?></h2>
						<?php the_content('content'); ?>

						<?php endwhile;

						else :
							echo '<p>No content found</p>';

						endif;
						?>
			</div>

			<!-- 01/11/15 creating column to put sidebar on the right -->
			<div class="column2">
				<?php get_sidebar(); ?>
			</div>
			<span class="clear"></span>

		</div>

	</div><!-- /site-content -->

	<?php get_footer();

?>

Is anyone has an idea why?

Thank you
