In Back to the Future why do we instantly buy the relationship between Marty and Doc?

Maybe this is more of a screenwriting question but it’s only been fairly recently that comedians like John Mulaney and shows like Family Guy have pointed out how odd it is that there’s no backstory between the characters of Doc and Marty in Back to the Future, yet I don’t know anyone who needs or cares for an explanation about how and why they’re friends. What is it about this relationship that makes us buy it instantly without explanation?
