I would cringe if the ancients came here via time travel and ended up at the womens march...

I'd be afraid they'd all drink hemlock to prevent it!
LOL

I agree with blarman: Ancient peoples were as smart as we are. They had tools and techniques we have not recovered, because they were made of wood or because they were knowledge based or because they were rare - such as the vicegrips in the Norse Mastermyr toolkit from about 1000AD.

No need for aliens; we have brains.

These objects and others were the inspiration for my novel series The Vostok Revelation (First Contact book 1) There are far too many sophisticated, out of context and dismissed objects (building, devices, images) for it to be ignored. I found that it was interesting to weave together a great many of these things with other human beliefs to create a compelling story. I suspect the truth of the matter is far more interesting than anything I can speculate.

The precision with which some of these megaliths are constructed suggests some very sophisticated tools both for measurement and machining. Where are they?

The History Channel under the aegis of "Ancient Aliens" has covered these locations and always attribute the immense weight of the stones to aliens who used some force such as anti-gravity and tools that can make incredibly accurate cuts. If only we had a time machine.

Has the tendency to dispel the notion that ancient civilizations were really as barbaric and "primitive" as "modern" science would have you believe.

No, but that relationship does show up a lot in a lot of monoliths, beyond the one in 2001.

Yea, Giorgio has some real bad hair days. He also got mixed up in a cat fight amongst ancient alien enthusiasts, over some trivial thing. Not surprising after watching the sharks all start circling Harvey Weinstein, and now Jeff Bezos.

Plenty of enigma's with the ancient megaliths . Here is one that is first a tunnel carved into the base of a mountain . Next mined 300 miles away over two dozen perfect granite rectangle boxes 80 tons apiece with 20 ton lids.They were transported and brought into an opening and narrow tunnel.
The dimensions 13 1/2 feet long 7 1/2 feet wide and 11 feet high.. the cave entrance 9'10" wide not much room to carry on each side about 15" each side for carrying.
Serapeum of Saqqara .
So what is so fascinating about Saqara’s Serapeum? Lots, but probably most especially the twenty four enormous sarcophagi, measuring 4m long, 2.30m wide, 3.30m high and each weighing over 80 tons, made of granite. The Serapeum is an underground development comprising a complex network of narrow tunnels within which the large sarcophagi are located. It is baffling to think how these sarcophagi were ever moved and positioned within such a tightly confined space. Clearly not impossible, as proved, but how?

The sarcophagi too create their own mystery. Only two of them bare any inscriptions. The others are totally smooth in finish. Each is carved from a single block of granite. The corners are perfect inside and out, and the sides are said to be exactly parallel, which, even if there were actually some slight wavering and error in the remark, would remain remarkable with only primitive tools and no drill to have used that anyone knows of. Apparently there are notches that allow the 4.30m wide lid to be rotated sideways on its central axis and to remain in position on the edge of the sarcophagus. This indicates that the sarcophagi were used open as often as closed.

Ancient space aliens at least helped out with all that.
Just ask the electronic universe does his hair guy on The History Channel~

I want to watch it later to see if their dimensions are 1 x 4 x 9.

Well, he does point out how that theory doesn't pan out always, the brute force concept is unusable in some instances, like the tiny ridge where Cusco is located and he said " They don't know how they fit them all up there". So, if Plan A doen't fit, basic problems solving says "try a different idea". That is what mainstream science seems to want to ignore. But yes, just like the banksters today.

Pharaohs understood that when slaves were kept busy and tired they were less likely to revolt, just like the banksters today.
