My head-canon here is that time in the Star Wars universe is measured by something smaller than human (earthling) scale. Like if Coruscant has a 90-day year, or some short-lived species had an outsized influence on measuring time and/or standardized the galaxy’s calendar. Or maybe humans are one of the most long-lived species around. So, one or two human generations works out to be “a long time ago.”
