doing changes in page.php does not disables comment section..

Okay so I am not using child theme. I am making changes in the original files of the thirtythirteen theme. I tried to commenting out the comments_template() function, even tried by removing that line and saving the work but still the comment section is there in the page. I have opened functions.php file for checking but there is no function named comments_template(). I was able to change the code of style.css and it was working fine then, but this step of comments_template(), has made me stuck here for long. Following are the files-
