In the past, a human generation has been considered to be 20-25 years. Older genealogical documents will use these numbers. However, genealogical studies have revealed that this is too simplistic and can result in large inaccuracies during statistical calculation.
Remember, a generation and a lifespan are not the same. A generation is defined as the time from a manâs birth until the birth of his first child, not until his death. There isnât any Biblical support for either a 100 year generation or a 100 year lifespan. Psalm 90:10 says the average manâs life span is 70-80 years, and thatâs where I got the number from. Those who advocate a 100 year generation usually cite Genesis 15:12-16 where 400 years and 4 generations are both mentioned.
