I don't want to see my iPhone's files on my Macbook

Whenever I open Finder on my Macbook, the "Recents" folder is filled with stuff I have downloaded on my iPhone. I do not want this. I need my iPhone and my Mac to be two different devices. I still want to have files automatically saved in iCloud, for memories that I can look back to. But I do not want to see all this garbage from my messy iPhone in my new clean Mac. What should I do?
