In those days, when an author wanted to tell his audience that a person was important and worthy of honor and praise, they used a literary device common to the time. They gave the person an extremely long live span. The biblical authors were positively parsimonious with such expressions of praise and honor … the other peoples of the middle east had kings living 30,000 years.
Scripture is FULL of such literary devices and if you don’t learn them you will never understand the truth that scripture teaches.
I gotta ask, when did the Fundamentalists invade the Church and hook Catholics into a literalist hermeneutic?
The rant above was not directed at the OP, who at least asked the question.
