Hi kaylai,
it’s essential to understand that the file index.php handles archives. Your front page is not an archive, but a static page with widgets and there is no such pagination for pages in WordPress.
Instead of using a static front page, you could enable “Your latest posts” in your WordPress dashboard under Settings => Reading and then you’ll have the pagination you’re looking for.
For the static front page there is no such thing. However, if you are familiar with coding, you could of course code a pagination for each widget, but that is a different story. In case you want to hire a developer for customizations, you could have a look at WordPress Jobs or Codeable.
