...Like, they did that in reality, or that's what the myths say? Either way, it's totally nuts. I've been cornered at parties before but otherwise sane-sounding individuals who have accused me of being part of the government's conspiracy to suppress archaeological evidence that the Sumerians were aliens. At that point it's best to just smile and nod. Reading cuneiform is really fun for nerds like us but it's certainly not THAT exciting.
For some background on that, the person who wrote the original ancient aliens type books that the show is based on (Zechariah Sitchin) claimed to be able to read Sumerian and Akkadian writing and came up with some really wacky conspiracy theories based on his own translations that were just like... not real. Something about twelfth planets and Annunaki. I saw his book on someone's bookshelf once and picked it up and started reading. His translations were just... gibberish. The show ancient aliens is much worse. I've seen them bring up "artifacts" from places like South America with fake cuneiform on them that doesn't even remotely resemble the writing system. At least Flat Earthers have access to real information and are just willfully ignoring it. People who believe in ancient aliens are relying on con artists who claim to be credible because they're not actually able to evaluate the evidence themselves. If not for that aspect of it I would just think it's funny.
I'm taking a chance here so hope you are not LDS. If so, please forgive, the following is just my opinion. The original Prophet, Joseph Smith, translated some Egyptian papyrus and came out with an entire scripture. The scripture he wrote is quite striking, however. But he made copies of the original Egyptian he translated from back in the 1820's. And now it's very clear that his translations were pure fantasy. And yet people believe.
Actually, I'm going to write a post, tomorrow I think, on beliefs and why it is so difficult to drop them even when confronted with facts that prove them, the beliefs, false. It's way more than just cognitive dissonance.
I once worked for a man who did original research into some of the globalist elite's formal associations. It was amazing how many subsequent authors picked up his information, tweeked it a bit and called it their own. I know this happens all the time on YouTube. Unfortunately people who follow the various theories from one YouTube channel to the next think that just because more than one person says "it is so" then it really must be so. Humans!
