in my public_html i have 0 files. but if i go to public_html/ home, my website is in there.

so if someone goes to my website ( url.com ) they will get a blank page, unless they type url.com/home

so how can i fix that?

I gave you the solution already.
Place a .htaccess file in your main directory with the contents.
