ELI5: if the population was down to just a mere handful of humans left how many couples (man and woman) would it take to repopulate the earth without having any inbreeding in order to get numbers back to where they are today?

There'll always be *some* degree of inbreeding. Even today you might well be distantly related to everyone you meet. 

The issue is one of genetic viability through variety. I've see people estimate the number of *couples* needed to maintain genetic viability could be as low as 32.
