I think the bell-shaped things may represent lotus flowers, a design they used a lot in ancient Egypt.

You shouldn't assume you know what other people do/have done with their lives.
^Sir the guy just proved HIMSELF that he is UNFAMILIAR with the topic on a surface level. Right after he PRETENDED THAT HE JUST SPENT SIXTEEN YEARS STUDYING IT.

That's not the meaning of iridescent.
An iridescent object is an object that appears to change colour with changes in light (or changes in the object that change the way light is reflected/refracted by it, like in the case of soap bubbles.
Maybe you meant translucent?
Where exactly did I "prove" I am unfamiliar with the "Covid Comet" hypothesis, the work of Firestone etal, or any subsequent research into the subject? And where did I say I had been studying it for 16 years?
(I said I'd been following the subject since it was first proposed)
Try making calm, reasoned responses rather than shouting and making on ad hom attacks on those who disagree with you. It's better for the soul, as well as your credibility.
Anyway, I see we're now on to Libyan desert glass.
It's probably a moot point as to whether the origin was an actual meteorite impact or an air burst, given the event occurred about 28.5 million years ago.

And yes, we can date it:

No, it can't be definitively dated.
And the entire Impact Theory of the Younger Dryas... which YOU PRETENDED to have studied 16 years... the entire theory is BASED ON THE FACT THAT THE LIBYAN DESERT GLASS CAN'T BE DEFINITIVELY DATED.
The Impact Theory is that the Libyan Desert Glass came from explosions 11,000 yrs ago, which triggered the Younger Dryas time period.
The Younger Dryas impact hypothesis (YDIH) or Clovis comet hypothesis posits that fragments of a large (more than 4 kilometers in diameter), disintegrating asteroid or comet struck North America, South America, Europe, and western Asia around 12,850 years ago, coinciding with the beginning of the Younger Dryas cooling event.

Obviously the entire theory wouldn't exist if the glass was definitively dated MILLIONS of years ago, instead of potentially being created only 11,000 years ago.
Well, given it has been dated to millions of years ago
But in any case, Libyan desert glass has no bearing on the veracity or otherwise of the "Clovis Comet" impact hypothesis.

^It can not be definitively dated.
That's why The Impact Theory of the Younger Dryas incorporates the Libyan Desert Glass, as having been created 11,000yrs ago.
That's possible BECAUSE the desert glass can't be definitively dated.
But in any case, Libyan desert glass has no bearing on the veracity or otherwise of the "Clovis Comet" impact hypothesis.
^It's a fundamental part of the Impact Theory hypothesis, and it's potential proof of the theory being true.
All of which you'd already know, if you had followed the theory for 16 years, as you pretended.
It can, what do you know about Geology?
Your dismissive attitude regarding people that are interested/studied/study/work in specific fields you (apparently) know nothing about only makes you look bad.
Read this:

Evidence that adds further to the credibility of this hypothesis includes extraterrestrial platinum, which has been found in meteorites. There are multiple sites around the world with spikes in levels of platinum that can be associated with the impact hypothesis, of which at least 25 are major.[117] Although most of these sites are found in the Northern Hemisphere, a study conducted in October 2019 has found and confirmed another site with high platinum levels located in the Wonderkrater area north of Pretoria in South Africa.[118] This coincides with the Pilauco site in southern Chile which also happens to contain high levels of platinum as well as rare metallic spherules, gold and high-temperature iron that is rarely found in nature and suspected of originating from airbursts or impacts.[119][120][121] These Southern Hemisphere high platinum zones further add to the credibility of the Younger Dryas impact hypothesis.
Geologic origin
The origin of desert glass is uncertain. Meteoritic origins have long been considered possible, and recent research links the glass to impact features, such as zircon breakdown, vaporized quartz and meteoritic metals, and to an impact crater.[2][3][4][5][6][7][8] Some geologists[9] associate the glass with radiative melting from meteoric large aerial bursts,making it analogous to trinitite created from sand exposed to the thermal radiation of a nuclear explosion. Libyan Desert glass has been dated as having formed about 29 million years ago.[10] Like obsidian, it was knapped and used to make tools during the Pleistocene.[11]
The glass is nearly pure silica which requires temperatures above 1,600 °C to form – hotter than any igneous rock on Earth.However, few mineral relics survived from whatever caused the melting, including a form of quartz called cristobalite, a rarely occurring high-temperature mineral; and grains of the mineral zircon, although most have reacted to form a higher-temperature mineral called zirconia. Ideas about how the glass formed include melting during meteorite impact, or melting caused by an airburst from an asteroid or other object burning up high in Earth's atmosphere.

So there's quoting the Impact Theory evidence in Africa, and quoting the theory of the Libyan glass formed from impact explosions.
So really, this is splitting hairs... There's Impact evidence in S. Africa, and also impact evidence in northern Africa (Libya)...

But there is nothing to connect the LDG with an impact only ~13kya. Even the wikipedia page you quote states it formed ~29mya. Which no-one (except you) disputes.
The Earth has had thousands of large impacts over the past millions of years.

I know that the Libyan Desert Glass is a fundamental part of the Impact Theory of the Younger Dryas time period, stating that the glass was formed 11,000 years ago, from explosions that caused the Younger Dryas.
I also know that it's a respected theory in mainstream science.
All of which is proof that no, the glass can't be definitively dated to millions of years ago.
If it could then there would not be the Impact Theory of the Younger Dryas, incorporating the Libyan Desert Glass as evidence of the explosive impacts that caused the Younger Dryas, 11000 yrs ago.
Actually the guy looks worse if you BELIEVE his claim that he studied a theory for 16 years, without learning what the theory was.
^Thanks, well... regardless of that specific quote, it's definitely part of the theory that it struck in Africa, too, and created the Libyan Desert Glass.
I did quote earlier that there's supportive evidence of the Impact Theory in South Africa:

If I must, I will eventually find an article that is EXPLICITLY calling the Libyan Desert Glass formed from the Younger Dryas Impact Event... because it is truly part of the theory... and I'm surprised at the hair splitting anyway.
ArMaP already quoted the Impact Theory exploding all over the world (without specifically saying Africa), and I've quoted the Impact Theory evidence in South Africa, and I've quoted the Libyan Desert Glass as impact-evidence itself.
There's not much lacking right there, as it is.
I'm surprised if anyone can't see that it goes together very easily. Impact damage is established in S. Africa, and around the world, and there's also impact-remnants in the northern Africa... and people want to single out the one spot of impact damage from the others, and argue that it CAN'T possibly be related to the OTHER impact damage in the SAME CONTINENT and around the world... Hmmm...
So, as you didn't answer my question, I suppose that means you know nothing about Geology, as demonstrated by many posts on this thread...
Don't change the subject, I am talking about you.
South Africa is not Libya. I suppose Geography is not you forte either...
A tooth ache can be a result of an impact, but that doesn't mean that if you are hit in a knee with a baseball bat you will get a tooth ache.
It's not splitting hairs, it's being based in facts instead of wild imagination and ignorance.

I haven't even read half the posts in the thread, and everything I've been talking about has been backed up with links to information validating it, from mainstream science.
You're talking about me criticizing the guy for claiming he followed the theory for 16 yrs but he also didn't actually know the basics of the theory.
Apparently it's my forte more than it is yours, lol.
For god's sake, South Africa is South Africa. And Libya is NORTHERN AFRICA.
That's why it's relevant, IT'S THE SAME CONTINENT. So mentioning S. Africa's established Impact site, is establishing that THE CONTINENT of Africa HAS IMPACT DAMAGE from the Younger Dryas Impact.
^Well, as I've been saying, there's established impact damage from the Younger Dryas Impact event, around the entire world, including Africa, and then there's this OTHER melted glass IMPACT SITE, on the same continent, and it's really absurd to try to single it out like this, and act like it can't be part of that same impact damage that's everywhere, INCLUDING AFRICA.
^Yes, it's splitting hairs to argue that an impact site in northern Africa can't be related to the established Younger Dryas Impact site in South Africa, the same continent. And which has already been established, with evidence, from around the entire world, it IS splitting hairs and it's absurd.
...And I didn't make the connection myself anyway. I learned about the Younger Dryas Impact Event as incorporating the Libyan Desert Glass impact site.
But you guys gotta acknowledge the absurdity that there's Younger Dryas Impact evidence EVERYWHERE, INCLUDING AFRICA, and you're trying to single out a SPECIFIC SITE IN AFRICA, as not being related to that. It's definitely absurd.
Wrong.
I seriously doubt it...
And their closest locations are separated by around 5000 Km. And one is in the South hemisphere and the other in the North hemisphere, with all the differences that makes in atmospheric conditions.
The dates (that you keep ignoring because it suits you) are completely wrong.
OK, where did you get that information? Have you checked it recently to see if the information is like you remember it? Have you checked it to see if the person(s) that mentioned it changed their mind(s)?
Absurd is treating two events separated by millions of years as if they occurred at the same time.
PS: one suggestion, take care of your real life problems first, that will be better to all.

So that's the mainstream science of the original topic, and yes, it's completely well-established, what we're talking about: the unique landscape in China, as per the embedded documentary.
What's not 'proven" is my personal response that I interpret artificiality in the mountains, caves, and "mystery holes."
However what IS proven are the signs that I think show artificiality. The mountains' consistency of shape & size, the mountain that looks exploded, with caves inside the crater, and the mountain with the gaping hole. That's all proven to the extent that the video is SHOWING, crystal clear, what those aspects are, which I think artificial.
It's the side-topics which I haven't established as clearly, because... it wasn't the original topic.
So... I haven't proven that the desert glass impact site in northern Africa, is directly linked to the Younger Dryas Impact sites that include S. Africa, and also includes practically everywhere else in the world too.
So I haven't proven THAT, because it's a side-topic, and I haven't put time into it yet (as per real-life being demanding of my time).
But I did establish the Younger Dryas Impact site in S. Africa... the same continent as the Libyan Desert Glass... and I also established that the Libyan Desert Glass site was apparently formed from incineration & explosions. I established BOTH of those things, with mainstream scientific evidence, linked in the thread.
And also, you and I have both established that the Younger Dryas Impact sites... are found, practically everywhere, around the entire world. And so, when you take into account S. Africa, it ends up that the Libyan Desert Glass site, is practically SURROUNDED by the entire world of Younger Dryas Impact sites... which does indeed make it absurd to be so insistent that the glass-impact-site, is just IMPOSSIBLE to be related to the entire world of Younger Dryas impact sites surrounding it...
So... that's the break-down so far, everything is backed up with links to mainstream science, and the only thing lacking, is the side-topic of proving a connection between the Libyan Desert Glass etc., because that's a side-topic that wasn't originally a direct part of the OP and original topic.
So it doesn't really make THAT much sense to complain about side-topics lol because there will ALWAYS be side-topics that the original post didn't cover, lol. The original post can't cover EVERY SINGLE POSSIBLE side-topic, lol.
Well you were just apparently arguing that it's not RELEVANT that there's proven Younger Dryas Impact site in the same continent, as the Libyan Desert Glass impact site... so that's not flexing a lot of forte for geography... It's entirely BETTER forte to acknowledge, there's YD Impact damage ON THE SAME CONTINENT, and also, there's the ENTIRE GLOBE of YD Impact sites, practically everywhere on Earth, practically SURROUNDING the Libyan Desert Glass site... which geographically suggests that the one impact site JUST MIGHT BE RELATED TO ALL THE SURROUNDING IMPACT SITES, including the same continent, sheesh.
It established YD Impact in Africa, and also, in the ENTIRE WORLD surrounding the Libyan Desert Glass site, if you look at ALL the YD Impact sites, it's practically the entire world. And then the Libyan site is one more impact site, that you want to assume just CAN'T POSSIBLY be related, the whole world of impact sites around it...
Actually I just haven't sunk the time into the side-topic yet. And I didn't make the connection myself, it's how I first learned about the Younger Dryas Impact Theory, as incorporated the Libyan glass site.
^I've barely even gotten into this side-topic...
^Absurd is assuming YOU know, for sure, the millions of years history behind different impact sites... or that any human being really can be definitive about such claims...
^Thanks, I seem to have cleared up my phone's lack of charging, intermittently, this past week. Though you're probably trying to be insulting, more than you care about my phone charging its battery, LOL.
And also, what you're really probably getting is that I haven't sunk enough hours into the thread yet, apparently, well what can I say. "Patience is a virtue."
If you really have some interest in the topic then I will eventually work on making that connection between the Libyan site and the ENTIRE WORLD of YD Impact sites that are surrounding it...
Impact hypothesis
Main article: Younger Dryas impact hypothesis
A hypothesized Younger Dryas impact event, presumed to have occurred in North America about 12,900 years ago, has been proposed as the mechanism that initiated the Younger Dryas cooling.[107]
Among other things, findings of melt-glass material in sediments in Pennsylvania, South Carolina, and Syria have been reported. The researchers argue that the material, which dates back nearly 13,000 years, was formed at temperatures of 1,700 to 2,200 °C (3,100 to 4,000 °F) as the result of a bolide impact. They argue that these findings support the controversial Younger Dryas Boundary (YDB) hypothesis, that the bolide impact occurred at the onset of the Younger Dryas.
New support for the cosmic-impact hypothesis of the origin of the YDB was published in 2018. It postulates Earth's collision with one or more fragments from a larger (over 100 km diameter) disintegrating comet (some remnants of which have persisted within the inner solar system to the present day). Evidence is presented consistent with large-scale biomass burning (wildfires) following the putative collision. The evidence is derived from analyses of ice cores, glaciers, lake- and marine-sediment cores, and terrestrial sequences.[115][116]
Evidence that adds further to the credibility of this hypothesis includes extraterrestrial platinum, which has been found in meteorites. There are multiple sites around the world with spikes in levels of platinum that can be associated with the impact hypothesis, of which at least 25 are major.[117] Although most of these sites are found in the Northern Hemisphere, a study conducted in October 2019 has found and confirmed another site with high platinum levels located in the Wonderkrater area north of Pretoria in South Africa.[118] This coincides with the Pilauco site in southern Chile which also happens to contain high levels of platinum as well as rare metallic spherules, gold and high-temperature iron that is rarely found in nature and suspected of originating from airbursts or impacts.[119][120][121] These Southern Hemisphere high platinum zones further add to the credibility of the Younger Dryas impact hypothesis.
