Like i understand there isn’t a lot of things for the heat from Stars to bounce off of but what causes Space itself to be cold? Is it naturally always cold and if so why?

Basically everything is cold unless it’s heated. Most heat comes from the movement of atomic and sub-atomic particles, which most of space is notoriously short of because it’s a near perfect vacuum.
