Yes, the “Home” page has hidden child pages that provide various functions for XWiki. I don’t recommend moving or renaming standard / default pages. For one thing, it will make the upgrade harder. You can hide the “Home” page from the Navigation Panel if you want, see https://extensions.xwiki.org/xwiki/bin/view/Extension/Panels+Application#HNavigationPanel . Best is if you create new top level pages where you put your content (as you started to do).
