Nice post. Per the time line, it appears Methuselah died right about the time the great flood started. Interesting. Might have made it more than 969 years if he had behaved.
Yes, if you add up the years (and i did one time in church as a kid when i was bored with the sermon), it turns out Methuselah died in the flood. That’s like your 95 year old uncle Murray dying because he got hit by a bus.
