Why did the people in the Bible live such long lives?

Throughout the book of Genesis, people are frequently described as having lived extraordinarily long lives, sometimes even hundreds of years. Adam passed away at the age of 930, while Methuselah, the oldest person in recorded history, lived to be 969.

God may have extended these early lives for practical reasons, such as the fact that there were fewer people in the world and a greater need to bear and rear offspring. War, famine, illness, and crime were also less "formalized" back then than they are now. The numerals could also be symbolic rather than literal, which is another possibility. The authors of the Bible frequently utilized rounded-off numerals as symbols. This doesn't imply accuracy; it only shows that they were using numbers in a different way than we are.
