Theme Pages vs Native Pages
Similar to my other question about menues, I am confused about Pages.
I installed the Blocksy theme, and now in the Customizer it shows me these pages:
But I haven’t created these pages, I have only created the following native pages:
I am confused about the relationship between the two. I thought Themes should only be concerned with the looks of things. Why are there extra pages? And which ones are more important? For example, should I edit the theme search page or create a native search page? I want my pages to only exist in one place, not some here some there. How can I wrapped my head around this?
