That's similar to many other things, which I can't describe, but have noticed.  So much that it's not obvious, or "officially" published.   Too many civilizations had traits of earlier ones from science to "machines" to medicine-ish in the first one.

The similar style of building/city construction,  the fact that buildings were actually built, when we're told they were all barbarian nomads prior to Rome.  Even that Official Story is ignored, and nothing about history is really taught, a drastic swing from when I was in high school we had to memorize significant dates, names, and places for the "important bits" of year 0 to 1985.  That got pretty dense after 1700s, which made me hate it.   I can see going into that much detail over memorizing dates is a good way to make people not want to know because they only think of history as More memorization of dead people and dates".   None of them really went into depth of why, or much on how, Just knowing the dates was the important part, and asking why got you detention for being a smart ass to the teacher.

I learn much faster, and see things better when I look at the who, when, how, why of things.   Then it all falls together and I can link chains for remembering dates, it makes sense and falls together.  Sadly,  some of that info isn't popular now as it was when King Tut was a big deal in the 1980s, with astrology in full swing and whatnot.

So, I explained, with exhausttive completeness everything I could when my kid asked me why, he still asks me why, so I guess I did a Good Thing there.   When any information can be put into context by an anology, it helps further.  Figuring out how you'd explain why or want to know the Why of things, causes you to learn ore which makes you more eager to learn more.  It comes frmo strange sources that sometimes give bullshit, but once the context and other 'whys' are in the air around it, some parts make a lot more sense, while some "theories" are crap, even those from Official Historians/Archeologists.  They must intentionally write their reports/findings/releases to be as dull and boring as possible.  Like more memorizing of dates, instead of explaining what other things/places/events also link together in it.

So @waterglass  Thank you.  Post more like the medical (or any field) that shows pretty clear links, if you have/find  them.

However, the second video, are they claiming they wasted ethanol as a weapon instead of a party?

Reading about telescopes today, and this thread jumped into my head...

Found this by clicking around linkes, Itink from here.

Top.  Men.

Sadly, part of me thinks the first two were by design, so the 3rd could be a convenient 'write off' made comically plausible.  It's been a running joke since the 80s, and not much has changed.  Any new or different old things found?  Give to Smithsonian Museum, where it can be protected from bad things like Oxygen, Sunlight, and the gaze of those "not-qualified" to see it.

Only way you could do it would be 100% privately funded, results given to "amateur" archaeologists as open source to tear apart/dig into/visit.   Just don't do anything involving .gov technology or aircraft (writing off space, basically), so the Smithsonian or other group "claim national security",  can't jump in and "save" what's found, to a place it won't be found.   Why would they have <40% inventory on display, 5% loaned to other museums temporarily, and 55% pretty much decided to not display at all, or again?  Why not donate that stuff to smaller museums in the US?   Why have they only digitized in Full VR only a few % of everything they have?  What good is preserving history if it's never shown again?

The reason we have so many strange "Ancient Aliens" shows is they can collect related items, not normally seen by the average hobbyist, then put them all in a video.  What they say doesn't matter much, mute it and look at what's shown, come up with ideas, looking at the info and images does.  It's like the safe way to show a different story, as long as there's enough looney in with it to allow it to get entirely discredited.

I see all  Mr. Aliens Dude as Court Jesters or Satirist actors, in many forms, from the birth of open secrets, almost a trait of humans, when framed in the time they live.
