Unfortunately we do have a good idea of how much survives from civilizations - based on what we've found of previous ones.
All civilizations use stone tools and they essentially last forever. We found habitation sites going back 100,000s of thousands of years, 400,000 year old wooden javelin, etc. Even an 'eco' civilization would have had a precursor development period and unless they went back and dug everything up - we'd find it.
Usually the claim that "nothing would survive" is made by people completely ignornant of archaeology and geology...and wishing to come up with something to deflect the lack of evidence.
If you disturb the earth the soil retains the memory of that (driving a stake in or digging it up, placing a foundation on top of it or building a fire) for an extremely long time - as do sediments which contains pollen which reflects how humans modify the enivornment.
Ever wonder how long a cut gem would last?
I'm not an idiot Hans,
it's pretty obvious that stone tools among other things could last practically "forever" under the appropriate circumstances but what makes you think that we as a civilization have dug up everything from the ground already?
What makes you so sure that the cost lines were where they are now?
Do we have any large dig in progress on the bottom of the Atlantic, Pacific, etc?
71.11% of the Earth is covered by water, only 28.89% isn't. And I would guess that we haven't dig anything close to 20% of these 28.89%.
Our civilization is still discovering animal life forms that are right on the surface of the earth, so thinking that we know everything that is bellow water and the ground is not only pretentious but ignorant.
Besides dating things based on their context (environment) is pretty much just making an assumption, a best guess based on what we think we know and take as correct.
And since we only think that we fully understand things on a chemical level any chemical analysis dating could very well be off in a margin that is not acceptable.
Everything in nature can mutate in a chemical level under the right conditions. So again this argument of that "x stuff would remain" it's just talk from people that don't want to see the big picture.

Hans: that appears to be your opinion yes
Hans: Did anyone say we have? Until we do an unknown and unfound item remains ‘speculation’.
Hans: ‘cost’ lines? Sorry don’t know what you are referring too, oh do you mean coast lines? Yes they go up and down
Hans: Do you? Nope didn’t think so, so there could be something or they could be nothing. Oddly things at sea tend to get washed ashore.
Hans: Yep, and so far we haven’t found anything that shows us there were unknown ancient civilizations, we MIGHT find something in future but for now we have nothing. Not having found something doesn't mean it exists!
Hans: Imagining that in the areas we don’t know about there MUST be proof of lost ancient civilizations is pretty silly. Why not base what we know on what we have and leave the rest to speculation?
Hans: Comparative analysis gives one a clue as to the relative age. I know that archaeologists will be deeply hurt that they don't have your confidence.
Hans: Oh my you appear to be absolutists – we can’t know everything in complete and absolute detail therefore we know nothing….except for your opinion that unknown ancient civilization MUST exist.
Oxidation - requires oxgyen
Wooden javelins survived for 400,000 years
400,000 year old javelins
How do stone tools oxidize? Do fossils oxidize? Obviously not.
Time will destroy all materials ultimately but within in the time frame things do survive.
If nothing survives Thomas how do you know ancient unknown civilizations exist?
I agree but that doesn't make what we have and know as "THE LAW", and certainly not enough to refute or dismiss others ideas that you can't disprove.
Bom eu tentei escrever em inglês mas você por sua vez resolveu pagar de otário corrigindo um mero erro imbecil. Isso demostra claramente que a sua resposta é falha e no mínimo incompleta.
Didn't knew that Yonaguni was washed ashore, I'll have to check that.
Agreed. But so far we haven't found anything to disprove it either,
or even explain certain facts that we already know about.
So if the possibility still exists the questioning still valid don't you think?
No body is saying that there are proofs of ancient civilizations in areas that we don't know about. All I'm saying is that it COULD be proofs of ancient civilizations in areas that we don't know about.
The possibility of not having them is exactly the same as having them,
which is enough to keep some of us open for possibilities.
This is a childish reply, don't you have something interesting that proves my point as being completely wrong?
All I'm saying is that we can't discard possibilities based on a knowledge that is not complete and certainly limited.
But if you think we already found all of the ancient civilizations that's you're right and I won't argue.
So I would say you're are the one talking in absolutes here.
Closing your mind to stuff is just another form of ignorance.
Steel
India has been reputed for its iron and steel since Greek and Roman times with the earliest reported finds of high-carbon steels in the world coming from the early Christian era, while Greek accounts report the manufacture of steel in India by the crucible process. Wootz is the anglicized version of ukku in the languages of the states of Karnataka, and Andhra Pradesh, a term denoting steel. Literary accounts suggest that steel from the southern part of the Indian subcontinent was exported to Europe, China, the Arab world and the Middle East. In the 12th century the Arab Idrisi says ‘The Hindus excel in the manufacture of iron. It is impossible to find anything to surpass the edge from Indian steel’.
Studies on Wootz indicate that it was an ultra-high carbon steel with between 1-2% carbon and was believed to have been used to fashion Damascus blades with a watered steel pattern (Srinivasan and Griffiths 1997). Experimental reconstructions by Wadsworth and Sherby in the 1980’s have demonstrated that ultra-high carbon steels with about 1.5% C can be used to simulate blades and that these exhibit fascinating superplastic properties. Superplasticity is a remarkable phenomenon which allows a material to change its external shape to a very great extent without changing within.
A description from the Crusades of the Damascus blades is as follows: ‘One blow of a Damascus sword would cleave a European helmet without turning the edge or cut through a silk handkerchief drawn across it’. One sixth century writer describes blades as having a water pattern whose ‘wavy streaks are glistening-it is like a pond on whose surface the wind is gliding’.
Wootz steel also played an important role in the development of metallurgy. Michael Faraday, the greatest experimenter of all times, tried to duplicatethe steel by alloying iron with a variety of metallic additions including noble metals but failed. As he was the son of a blacksmith the extraordinary properties of Wootz steel must have fascinated him. His failure had an unexpected and fortunate outcome as it marked the beginning of alloy steel making. Wootz has been a prime motivating force in the development of metallurgical science and the study of micro-structures. Although iron and steel had been used for thousands of years the role of carbon in steel as the dominant element was found only in 1774 by Tobern Bergman and was due to the efforts of Europeans to unravel the mysteries of Wootz. Similarly the textured Damascus steel was one of the earliest materials to be examined by the microscope. British, French and Russian metallography developed largely due to the quest to document this structure. Wootz was an ‘advanced material’ of the ancient world used in three continents for well over a millennium. Neither its geographic sway nor its historic dominance is likely to be equalled by advanced materials of our era.

Following the “Beacon”
When viewed from a nonscientific standpoint, the Delhi Iron Pillar’s ability to resist corrosion has often been called a “mystery.” Balasubramaniam is quick to dismiss this response. “There is nothing mysterious about the iron pillar,” he says. “The resistance to atmospheric corrosion is due to the presence of a relatively high amount of phosphorus in the pillar. The remarkable corrosion resistance can be understood by applying the basic principles of corrosion research.” He adds that the direct reduction technique used to produce the iron is no mystery, either. “The ancient Indian ironmaking technology is well-known,” he says. The established scientific facts notwithstanding, Balasubramaniam concedes that one feature of the pillar is difficult to explain. “There is one aspect that is not well-understood and this may be called a mystery, in one sense,” he says. “This is the method by which the iron lumps were forge-welded to produce the massive six-tonne structure.”
Mystery or not, the Delhi Iron Pillar serves as a guidepost for metallurgists in the 21st century and beyond, asserts Balasubramaniam. In fact, just as a seminar at RPI inspired him to study the pillar, he hopes that his research will motivate others to explore the potential uses of phosphorus-containing iron. “There are so many wonderful options available with phosphoric irons,” he concludes, adding that the Iron-Phosphorus phase diagram deserves as much attention as the more popular Iron-Carbon phase diagram. “There is an exciting future in developing phosphoric irons, particularly for corrosion scientists and engineers.7 The beacon of light showing the way to the future is the Delhi Iron Pillar, with its tested proof of corrosion resistance.”
Hans: Who said it was the law? Its very simple Thomas we don’t evidence of unknown civilizations
Okay? We firm on that concept now? LOL
1. If we don’t have evidence of them that means
2. We don’t have evidence for them
3. That means
4. They either don’t exist
Or
5. We haven’t found evidence of them
6. They might exist but at this point we don’t know
Why are you having such a hard time with this concept? Go thru the numbered items, read them slowly, get an adult to help you
Hans: I wasn’t born in a english speaking country either
Hans: Items from off shore tend to move in the direction of wave movement. Simple science, that is why sea shells, pottery shards, stone tools and coins show up. Yonaguni is a rock don’t think it will move
Hans: Ah Thomas that is classic error of trying to prove a negative. So tell me how would we find something that would disprove that ancient unknown civilizations don’t exist? Be specific! LOL
Hans: Such as? I suspect I'll get back a flood of fringe webpage nonsense
Hans: The question is also valid but the answer is speculation until evidence is found
Hans: Yes that is called un-evidenced speculation which has been my point all along
Hans: sorry that doesn’t make much sense
Hans: Speculation is always open what is your point?
Hans: It was a childish question
Hans: No one has ever said that – you seem to be arguing with no one about nothing – who is discarding possibilities? If I point out we have no evidence for these lost civilization that doesn’t discard the possibility we will find something in the fuure - what is it about that concept you cannot seem to grasp?
Hans: Ah Thomas I said no such thing, stop making stuff up, I said (repeatedly) we have no evidence for unknown ancient civilizations – why do you find that so hard to understand.
Hans: Not at all you don’t seem to even understand what we are talking about
Hans: Thomas do you even known what we are talking about?
You talk a lot of BS and you're good it, i'll give you that.
No, that particular pillar was not erected in the 5th century, it was erected in the 4th century and there other pillars all over India with the same anti-corrosion technology.
It is interesting how you completely overlook something as amazing as anti-corrosion of pure iron(98% iron) and ancient steel using nanotechnology.
It's clear for everyone here to see you're not even considering this evidence.
I have no idea where you got the "probably Chinese technology" unless your're Chinese yourself and feel a bit undermined that the Indians were creating steel and zinc.
I don't want to start an India vs China war, but its pretty clear Chinese culture was heavily domainted by India in the past.
Hans: Ah Indigo, the pillar was made by HAND hammering disc of metal together, they used a technique of forge welding. Oh and I've seen the pillar in Delhi - you can still see the hammer marks in the right light

So why are saying “nanotechnology” when it was beaten together with hammers?
Hans: sure I considered your Iron pillar evidence and have shown it was wrong –
Hans: I don’t think so, they tended to share with China being the leader in many technological fields.
Those are not hammer mark, they are the impact of a cannon ball that was shot at it by an invading Mughal king in attempt to knock it down.
he explains.te this expert is saying this is post-21st century technology? No you probably didn't. That is why I've emboldened and underlined it for you.

Read the information provided to you again. When did I say that the iron is using nanotechnology? I said the steel was using nanotechology. I even separated the two in my summary.
No you didn't. You did not at all acknowledge that this is pure iron and it has not corroded in 1600 years, a technology we do not have. Like I said before you're being exceedng ignorant on a level I have not seen even on ATS.
I know about China contributions in technology. I am not invalidating them at all, but you certainly are invalidating India's technology.
China was culturally dominated by India this is a well known fact, and that is all I was demonstrating. Anyway this point is irrelevant to this discussion.
