MEGALITHIC STONES at YANGSHAN QUARRY - CHINA

Thanks.

But statistics are not proof of any thing.

Its information

Its information

True, and the more information we have the better.

But in this case I don't think that's important information, as the general randomness of a person's movements doesn't create patterns and gives an uniform look to things like that.

Also, we should never underestimate how good someone that does some thing all the day, every day, can get at their work.

Statistically the uniformity of the scoop marks is not explained by the use of pound stones.

Nope, given there were pounders found there and the hammer stone technique was used in many other cultures and left the same type of marks, and the Egyptian art shows it. I'd say the 'statistics' are wrong. https://i.imgur.com/wT3j2K0.jpg, Tiwanaku, https://i.imgur.com/Pm0PCjj.jpg, Egypt, https://scontent-sea5-1.xx.fbcdn.net/v/t...e=6A3360D1, https://i.imgur.com/5EtqUV8.jpg 

Survivorship Bias (Cat Injuries): A famous 1980s veterinary study reported that cats falling from higher buildings (7+ stories) suffered fewer injuries than those falling from lower buildings (2-6 stories). This statistic was wrong because it only sampled cats that survived the fall and were brought to a clinic; cats that died from the highest drops weren't reported.
Flawed Sampling (The Kinsey Report): In 1948, the Sexual Behavior in the Human Male report claimed that 10% of adult men were exclusively homosexual. This statistic was wildly inflated because the sample pool heavily overrepresented prisoners, sex offenders, and institutionalized men, making it highly unrepresentative of the general public.
Correlation vs. Causation (The Nobel Chocolate Study): A widely cited 2013 study found a strong, statistically significant correlation between a nation's chocolate consumption and its number of Nobel laureates. The statistic is correct, but it is deeply wrong to suggest that eating chocolate boosts intelligence. Both variables are simply linked to a nation's overall wealth. Mean vs. Median (Average Wealth): When looking at data with massive outliers, using the "average" (mean) is often misleading. If a room has 99 minimum-wage workers and 1 billionaire, the "average" income of a person in that room is over $10 million. The statistic isn't mathematically wrong, but it creates a wildly inaccurate picture of the median person's wealth. Can you link to said statistic study?

Stone masons and Egyptian stone workers were probably parts of 'guilds' or families that did so passing expertise from father to son. Such experience would provide people who had been doing the work from when they were children - and they just might be rather good at it. I've done a bit of it and very hard on the wrists, elbows and shoulders. Timing the drop so you don't absorb the impact then 'catching' the stone to repeat takes some time to learn, also timing it so a 'sweeper' gets the dust caused by impacts out of the way or they cushion, and weakens the following blows, you also sometimes get bits flying off from other worker's strikes - which is a concern for your eyes.

Dont know what to make of this. The Unfinished Obelisk is discussed:

For centuries, one question has puzzled historians, engineers, and archaeologists alike: *How did the ancient Egyptians cut massive blocks of granite with such incredible precision?* Now, a bold claim suggests that Grok AI has uncovered the answer—and the evidence is sparking intense debate.

Grok AI Finally Reveals How Ancient Egyptians Cut Granite — The Proof Is Shocking!

Video displays multiple fake AI images of these "perfect" tool marks.
If you can't provide a real example, but you go ahead and create a video, then you are a lying con man by definition.

It's been determined they couldn't have done this by holding the stones in their hands and dropping them unless they were freakishly good at dropping and catching rebounds.
Now it's hypothesized that the pounders were attached to short handles, making the stress on hands, wrists, elbows and shoulders much more manageable.
Probably some of it had to be done with the drop and catch method though, due to constraints on how much room to maneuver exists in some tight spots.

Yep I used both method the 'Y' stick is easier but the other is doable, if difficult. Egyptian art shows the use of handles. I did this first on Easter Island when there was no archaeological evidence for handles but I haven't checked if any have been found int he 40+ years

I'd say the 'statistics' are wrong.

As you point in your post, the problem with statistics is the information in which they are based. If they used incorrect data or data not really related to the problem, then the result is useless.

According to this the "scoop marks" are not uniform in any way (@12:45) GIGO
