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?

Heat comes from stuff moving around a lot. Space is a void, no stuff exists in most of space, hence, no little things (molecules) moving fast. So any heat that you put into space dissipates super fast, becoming cold.
