How many times has humanity been wiped down to near extinction?

[toobfreak]

I just want to know one thing:

Who put the three car doors in the picture?

All that is missing is the door handle and side mirror (prolly worn off over the ages) and the window crank.

They probably had power windows by then.

How many times has humanity been wiped down to near extinction?​

BTW, last I heard, at some point, the genus homo (Sapiens and Neanderthalenis) reach a low point in Europe at one point where "humanity" may have come down to just a few tens of thousands.

One more environmental incident/stressor might have sent all of humanity off into the dustbin of time.

The supervolcano eruption at Toba 80,000 years ago wiped humanity down to a few thousand individuals

Looks a lot like the “handbag of the Gods” that are found in carvings literally al over the world

Just think what future archeologist would think about our society with nothing but the Crazy Horse Monument and Mount Rushmore after a couple thousand years. Nothing else we build would last.

Maybe Hoover Dam — and the 10 feet of high speed CA rail line

This is done with harder rock ... they've excavated the quarries where these rocks came from ... and the stone tools they used were still scattered about ... plus bronze is more than strong enough to do this ... don't you do any research? ...

Do you have a citation for the image? ... why do you believe this is inside an Egyptian pyramid? ...

No ... I don't listen to ChatGPT ... he doesn't replace education ... his answers depend strictly on the questions ... like a Tarot reading, he only says things you want to hear ... it doesn't replace actually research ...

"As far as hardness is concerned, limestone averages 3 to 4 on [the Mohs] scale of 1 to 10, and it's harder than gypsum but considerably softer than granite." -- "What Is The Hardness Of Limestone?" -- Hunker -- Mar 25th, 2022 ...

Why didn't ChatGPT point out this scientific fact? ... because ChatGPT lies ... Author C. Clarke got that wrong ...

Frank is specifically referencing granite. Bronze will not work on granite in that way. There are no rocks that can give you a polished surface, at perfect right angles.

Remember, to get that surface polish you would first have to have shaped that even harder surface to get the desired shape.

There are enough anomalies throughout the world that I have no problem accepting that mankind had achieved much higher levels of civilization in the distant past.

The rapid rate of technological development over the last 3,000 years tells me that the belief that man did nothing of note over the previous 30,000 is not credible.

Who did this? How long ago? For what purpose?

What I find curious is why people would have such a vested interest in explanations other than “yup, there were civilizations here on Earth before us”

Yeah, I don't understand it either. I find these historical anomalies fascinating.

The Egyptian pyramids are made of limestone ... the decorative granite panels were split out of the bedrock ... is it physically impossible to cleave granite at right angles? ...

Do you have a citation that verifies that image is from Giza? ... and care to guess how many folks are on the "inside" of this conspiracy? ...

By the way, I own a rock polisher ... glad to know it doesn't polish rocks ... what do you call the lustrous sheen on some rocks these days? ... you know, the ones hard enough to scratch granite ...

I'm not a geologist and maybe I'm using the Mohs scale wrong ... way to much jasper in my location, grinds granite up to nothing ... but that's tumbling, maybe a Moh value of 8 doesn't harm Mohs value of 6 ... I wouldn't know ... it's just common sense harder rocks break softer rocks, like jasper breaks granite ... or granite breaks granite ... I use jasper to break jasper ...

... or just import wrought iron from Asia Minor ...

Yes, you can break rocks with rocks. That's not what we are talking about. We are talking about polishing granite with exact 90° angles.

Nor am I talking about the Pyramids. Though even there, the construction is interesting. 70 ton blocks are used in the interior. The ramp you would have to build, to get those blocks in place, is almost the same size as the Pyramids themselves.

But that's a different thread.

If you have a rock polisher, you would also have a rock saw, that uses a blade with diamond edge to do the cutting.

Egyptians didn't have that.

Also, you most likely use tin oxide for your polisher. Guess what, the Egyptians didn't have that either. And your rock polisher will take up to two months to polish those cute little granite pebbles, depending on how fine a polish you want on them.

And, no 90° angles.

Granite breaks conchoidaly, that means it doesn't break along a plane, it breaks like glass. So, after you have cut your slab of granite, you get to spend a very long time polishing out the high spots before you get to make the slab nice.

Modern granite slab makers use enormous diamond saws to do that initial cutting, so get to begin the polishing immediately. Even with that, and the use of powerful electrical operated machines, the process takes days. On objects weighing a couple of hundred pounds.

Once again, the Egyptians didn't have that either.

Egyptians had quartz ... I asked about the Mohs scale ... if jasper is Mohs 7.5, and granite is Mohs 6.5 ... then we can use jasper to polish and cut right angles in granite ... or am I using this scale wrong ... you never said ...

I use carborundum for grinding, aluminum oxide for polishing ... just like telescope making ... yes, both are naturally rare and had to wait under the industrial age, and I believe all commercial products of these materials today are synthetic ...

Maybe we need a geologist to explain why the Egyptian quarries were full of diabase hammers ... {Cite} ... see in the image how the block was hammered out of the granite matrix? ... makes smooth surfaces and right angles easy ...

And a correction, that citation above claims iron tools arrived in the 26th Dynasty ... the Great Pyramids of Giza were build in the 4th Dynasty ... whether Hittite wrought iron was available to these quarriers is beside the question ... what remains at the quarry site are stone hammers made of harder stone ...

"Conchoidally" --- I know that's a word but it still makes me roll with laughter ... "chips like a seashell" rather than along distinct planes of cleavage ... geologists can be such comedians ...

You still haven't described how you shape the quartz to make the tool to carve the 90° angles.

How about you start there.

Everything else you are talking about are simple percussive tools. Those are well known. It is also well known that they don't do fine work.

We are only talking about the fine work.

I'll need the citation for this "fine work" ... the image itself comes without attribution ...

Egyptians stacked blocks on top of one another ... real easy to form these interior 90º angles ... the same way we do today, on top of flat walls we set flat ceiling joists ... at 90º angle ... perfect interior angles ...

I'll offer this video in her full 11 minute version in order to verify this is indeed a tour into the Great Pyramid of Giza ... at 7m45s we begin to transition from rough hewing to anything that resembles "fine work" ... and at 9m15s is a good place to start for what appears to be the finest of the "fine work" ... some stranger with a telephone posted this to Youtube is all I know of it ... it's just better than what you got ...

I might be a little outside my paygrade here ... but I think an expert with an optical microscope could tell you exactly how all this is carved ... and all that copper in that Telsa-style death ray underneath should have tell-tale chemical signature to where it was mined ... and if it was of alien manufacture, it would be contaminated with cesium ...

These are pictures of granite edifices on Elaphantine Island. No known date for when they were made, but it has been assumed that it is Egyptian. Feel free to show us anything the Egyptians did that is even close to this level of work. Notice the saw cut. The claim is they used sand abrasion to make those cuts. My question is how do you even start the cutting? There's nothing to focus the sand into the cut. Also, look at the precision of the cut. Copper saws won't do that in a million years. The second image shows the top part with multiple angles, all cut precisely. Once again, WE have a hard time doing that now, with massive grinding machines.

How did they do it with hand tools?

That's my question. Show us a method.

And you know it. There are many ancient discoveries found the world over that given the tools available at the time, absolutely boggle the best minds of today how they could have possibly carved, shaped, moved and fit such stones together, as no one could even do such work today using our best machinery.

 

[CrusaderFrank]

In each and every instance, there are mundane if labor intensive explanations that match the evidence that are far less flashy than 'buried coils' and 'levitation beams'. But work beautifully and were well within the technological capabilities of the Egyptians.

You can cut granite with quartz sand, water, copper saws and a shit load of time and expertise. And the pyramids are almost entirely sandstone which is even easier to cut being much softer.

You don't need levitation beams. You can just drag the stones up earthen ramps, or build the ramps into the pyramids themselves. The incline plane is hellaciously effective. And doesn't require aliens. Just basic physics.

This 'ancient alien' bullshit is an insult to the ingenuity of ancient peoples. They didn't need levitation beams and space lasers. They can do it with sand and strong backs.

You're starting to sound like a Japanese soldier lost in New Guinea since WWII and still thinks he's fighting for the Emperor.

Game Over.

The Pyramids predate their "Egyptian" builders AND the Great Flood

There's more architecture underneath the Pyramids than there are above them

The Pyramids don't. There is plenty of evidence that they were built by the ancient Egyptians, for the most part. There are some major issues with the interior structures, but the exterior of them is fine. I do have questions about the interiors however.

The Sphinx though, that exhibits classic water weathering features, while the Pyramids show wind based erosion.

The Pyramids had layers of salt on them.

"The evaporative cooling passage of the Great Pyramid of Giza and the Queen's chamber were discovered with a very hard encrustation of salt, up to one-half inch (1.3 centimeter) thick."

If I didn't know better, I would say that box could only have been made using a milling machine using a variety of face mills and cutters, and even then, I'm left puzzled about how they formed the perfect, smooth, 90° corners.
