Tried to create a custom page template for my home page and now get a 404 error I'm new to Drupal so I may have done something horribly wrong.

Using Drupal 7.

I tried to create a custom home page by using the Page builder. I created a page template and assigned it to be used as the home page. Then decided against and deleted the template. 

Now I get a 404 response when I go to my home page. The rest of the site works and shows all the pages. I tried clearing the cache but no luck.

Andy help or ideas would be greatly appreciated. Thank you
I figured out the answer. I needed to install the Panels module so that I could use it as a variant. And that allowed me to set my home page template the way I needed it to be. Sorry for any confusion I may have caused with my question. And thanks for the help!
