I am uncertain this is true, but for the sake of wonderment and mystery in this world I am going to believe it nonetheless.
Consider me intrigued, Madam/Sir Clown.
Our true history is much more wild, terrible, and wonderful than we've been led to believe.
The Indian religious texts describe the tech they were using, it just sounds so batshit insane that most people assume it's impossible.
But, look at the tech we're creating: magic was always just advanced science/spirituality.
The elements that rule our societies are remnants of these ancient civilizations, who hid their tech/knowledge, then used it to regain power once life began to rebuild post war. The Flood that wiped out the civilizations was the Younger Dryas around 12,000 years ago; the war that used a lot of nukes was 7,500 years ago.

That's why these creepy losers are in power: thanks to the knowledge they got from ancient civilizations, they have a very high level understanding of how the world works.
This is also why there are so many ancient libraries they won't let plebians into: Tibetan stuff, the Vatican's catacombs, the Egyptian tombs, etc.
Our ancestors understood how the world worked, but chose war over peace, blew the shit out of each other and the planet, and we're still suffering from the aftershocks.
In some ways, that war never really ended.
Authors/guides like Oda use stories to encourage people to uncover/research this history. Robin/Vegapunk serve to get us to research our history that has been stolen from us.
They are allusions to the many scholars and scientists who have been murdered/silenced for trying to uncover the truth and throwing mud on ridiculous official narratives that make no sense.
