The biggest reason I could find for hiding Atlantis and this advanced society was basically aliens. It's said that there's entire bases and civilizations in the South Pole where our governments are working with extraterrestrial populations and if that's where Atlantis was located, checks out. We could spend hours talking about the government and aliens so we'll just leave that be for now. But another piece of information that could have been important to suppress was the existence of this material called orichalcum, I'm not even sure if that's how you pronounce it, but something along those lines. The reason it's notable is because this doesn't occur naturally, it has to be processed from zinc and as far as we know, people didn't have that kind of technology back then. So the theory is that the people of Atlantis were taught how to craft this by extraterrestrial beings. So maybe this is another government alien conspiracy, what do we think?
