How to create custom blog template

Hi ,
i am trying to create a custom page template for showing the blog post .
This is my current code :

<?php
/*
* Template Name: Custom Blog Template
* Description : Page template for dysplaing blog posts

*/
?>

<?php get_header(); ?>

<?php get_template_part( ‘template-part’, ‘head’ ); ?>

<!– start content container –>
<div class=”row rsrc-content”>

<div class=”post-wrap”>

<?php

// theloop
if ( have_posts() ) : while ( have_posts() ) : the_post();

/* Include the Post-Format-specific template for the content.
* If you want to overload this in a child theme then include a file
* called content-___.php (where ___ is the Post Format name) and that will be used instead.
*/
get_template_part( ‘content’, get_post_format() );

endwhile;

the_posts_pagination();

else:

get_template_part( ‘content’, ‘none’ );

endif;
?>

</div>

</div>
<!– end content container –>

<?php get_footer(); ?>

The above code displays a page with title and “read more ” button but without posts. What am i doing wrong ?
Thank you
