ELI5: How can advanced countries have such different schooling times for doctors?

How can some countries like America have an 8 year requirement for doctors and others like Australia have 5 years, with equivalent qualifications? Also how can med school in america be hard after 3-4 years of science beforehand?

Why wouldn't they?  Being a competent doctor requires a lifetime of learning, first at elementary level, then through secondary and university, plus an internship, residency, and a lifetime of keeping up with advances and new information.  At what point, exactly, does one make a clear point of demarcation, where on this side the person is officially a physician, and on that side (s)he isn't?  Different countries draw that line at different places.  None are obviously and objectively more correct than others.  The point is that each is saying *"Here's a highly trained and educated person we've decided is qualified to be called a physician now.  Having just graduated, (s)he is still a complete newb, and won't really be any good at it for years yet.  But (s)he has passed the first level at least, so show some respect."*
