You’re right about the math but not about the reason. Metuselah means “His death has sent/unleashed” and the story is that God waited 7 days after his passing (the mourning period of shivah) before unleashing the flood.
So his dad Enoch conceived him when he was 6 ?
There are a whole lot of biblical ages that make more sense of you divide them by 2. Like Sarah’s age when she conceives, and Ishmael’s age when he and Hagar are sent out into the brush by jealous Sarah. And I’ve read serious scholarly suggestions that there was a confusion between seasons (of which there were 2 a year) and years, and some of those stories should be read that way.
But Methuselah was just miraculously old. And the number of Israelites who wandered around Sinai doesn’t make any sense.
Where is this story found?
So, while they were “easily” moving SIXTY-NINE BILLION POUNDS of stone blocks, they didn’t question why someone who was supposed to be a GOD was preparing to die, and they didn’t wonder why their GOD didn’t move the damn things himself?! Talk about redefining “gullible”! 
It’s important to note that they were being paid in bread and beer.
Joke answer:
If he did it himself how could they prove their faith, use their otherwise idle days between seasons and get paid in delicious nutritive beer?
Serious answer:
I suspect that the powers of the Pharaoh as god were not as extensive, he managed the flooding of the Nile, perhaps the rising of the sun, important stuff like that but was not omnipotent and could not move stones.
He can make the sun rise but can’t move a stone block?! Like I said, GULLIBLE!
I think I would have been classified as a trouble maker back then.
If you’re getting paid well, at a time when you’d otherwise be unemployed, do you care?
That’s a valid question, and my answer is yes. It’s “yes” because the beer and bread could have simply been given to them because a ruler is supposed to take care of his citizens, and it is “yes” because those riches could have been used to enhance their society instead of being buried with a corpse.
Because of the world in general and our nation in particular, I’m fed up with self-aggrandizement, greed, and the constant quest for power.
According to many historians that’s exactly what happened, “enhancing their society”, by the common effort of building the pyramids. They argue that it united and built the nation and state of Egypt, which became the longest lasting and cultural constant and unchanged empire in history. You can’t apply today’s standards and personal freedom to fellahin from 4500 years ago, especially don’t expect much critical thinking or doubting their and the Pharaos status. As someone else mentioned above, in their view the Pharao was responsible for the rise of the sun every day and the recurring Nile floods in spring. History shows that every time when climate changes caused droughts and the Nile floods failed to materialize, the Pharao and the whole Egyptian elite got into trouble, because those were the times when the people actually doubted the powers of the Pharao.
How exactly?
Your interpretation of the powers of gods and how they applied is very much a modern one I think, ancient people IMHO did not think that way.
And do you imagine that if you lived at the time your superior moral fibre would have just automatically known that this was all unfair? Or do these ideas you hold come from a long line of political philosophical thinking that simply hasn’t happened yet in 2,000 BCE?
Ancient Egyptians weren’t stupid or even gullible, they were just working with significantly less complete information about how the world works than you are.
This really reminds me of, of all things, an episode of SpongeBob. SpongeBob and Patrick find a baby clam (which in the SpongeBob world is the underwater equivalent of a bird) and SpongeBob points out that it can’t even fly yet, to which Patrick responds, “Why? Is it stupid?”
Many places, but one would be Rashi’s commentary on Genesis.
So that wouldn’t actually be in Genesis.
You’re right! I never said it was in Genesis, did I? Checks prior posts. Nope, I didn’t!
It’s also not in Harry Potter and the Prisoner of Azkaban or Little House on the Prairie.
I’ve never understood this “but that’s not in THE BIBLE ITSELF” retort; if you took all the Jewish beliefs and traditions that don’t come directly from Biblical text, you could fill a whole book. In fact, they DID.
Yes, and my Harry Potter or LHotP fanfic retconning doesn’t have any bearing on those stories either.
Rabbinical Judaism has for its entire existence been at least as much about the Mishnah as it is about the literal text of the Torah. I’m sure it’s fun to be hyper edgy and dismiss all that as “fanfiction” though, so don’t let me stop you.
Any sufficiently-old religion has a lot of the beliefs and practices tucked away in places other than the primary scriptures.
