How old was Noah when he entered the Ark?

Noah was 600 years old when he entered the Ark.

Genesis 7:6 states that Noah was 600 years old when the floodwaters came upon the earth. Genesis 7:11 gives an additional chronological marker, saying the Flood began in the six hundredth year of Noah’s life, in the second month and seventeenth day.

This age belongs to the biblical narrative’s chronology, whose lifespans are far longer than those generally recorded in modern historical populations. It should therefore be read as a specific textual claim rather than as a modern demographic statistic.

Noah’s age is also connected to the story’s later timeline. Genesis 8:13 says that in Noah’s six hundred and first year the waters had dried from the earth. Thus the narrative places the Flood’s beginning and the final drying of the ground across two numbered years of Noah’s life.
