Greetings, ATS!
Let me start with a caveat. This post is pure speculation. I have no sources, no quotes, no videos or links to support my theory. In fact, I hesitate to call this a "theory," because that would imply some scientific validity and I have none to offer.
So, what I would like to do is have a discussion with some of our more knowledgeable members about the likelihood that advanced civilizations existed, AND that we would find evidence of such existence today.
This is what I'm pondering. I'm 38 years old, and in my lifetime I've seen some amazing leaps in technology that I never dreamed of occurring. I've watched our society go digital, so to speak. The majority of our correspondence is now online, we archive important information and photos online, etc. Just one thumb drive can hold vast amounts of information.
As our society continues to advance, will the amount of "findable" artifacts decrease? For example....imagine twenty-five years from now a global cataclysm occurs and the few surviving humans are thrown back to the stone age. The infrastructure we depend upon is destroyed, perhaps buried in volcanic ash or washed away in great tsunamis.
Now imagine a million years goes by, and the survivors have advanced enough to be on par with our current level of technology. Would they find evidence of our civilization? Would anything be left to find?
I've watched the television show "Life After People" and it seems, to me at least, that most of our leavings would be gone in the fullness of time. Especially since a lot of our existence is now "in the cloud," so to speak.
What do you think, ATS? Am I completely deluded, or is there perhaps some plausibility in this scenario?
Gratefully,
smiley

Anything left behind, there will be archaeological evidence of it. Some things preserve and it's just a matter of time before it's found. It can't all be totally eradicated with time.
I think the more important question to ask is.."If someone found evidence of ancient advanced civilizations, will it be handled properly and made public knowledge, or will it be discarded and suppressed?"

1. Much older than "10,000 BC" the farther you go back the less distinct and precise the geological and other data becomes.
2. A human or other settlement that was very small, not more than 10-20,000 people. A civilization footprint increases by leaps and bounds as the number of people in it increases. If you can keep it very small it is easier to miss it.
3. No traveling or trading, if they are isolated and don't seek contact they then leave fewer artifacts and traces. People who do travel and trade leave lots of traces.
4. Complete destruction. The farther you go back the less accurate is science's detection of events. If you go back far enough sites can be subducted and completely destroyed. Human habitations and artifacts are rather difficult to destroy completely, for example look at Thera, a great deal survived an enormous explosion.
5. The colony used unknown technologies that left no trace - but this doesn't explain the traces that would have been left BEFORE they developed that technology.
6. Unknown source, ie this colony came from some unknown source other than human evolution. This is possibility but at present no evidence supports it. [ex/]

You are jumping to a lot of conclusions here...
The foundations of buildings could be the first things to go because water collects underground and doesn't dry up like it does above ground. The water would corrode and penetrate all the man made material below.
Also... even though we could know of million old mans remains that doesn't mean entire eras on Earth couldn't be wiped away and destroyed by catastrophes. Those million old eras could be protected by a calm environment before and after the era. If an era did NOT have a calm spell during it's time they could easily be destroyed without a trace.

A wooden stake driven into the ground will leave that impression in the soil and the sedimentary rock it hardens into - that will only be destroyed by subduction. How do you destroy kilometer long tunnels in granite? We made several hundred just in this civilization? So where are the old ones? Why don't we find old mines, precious gems, cut ones are all but indestructible - no sign of them, etc
Again you are using the 'it was all wiped away" but people at the same time contradict themselves by saying we have traces - so which is it? Castastrophes leave evidence of their passage and we have fossils and archaeological remains from many areas- if they were 'wiped' clean why are they NOT wiped clean?
Look at my link to the Bolomor site above.

Not a chance that evidence of us would be gone.
A decent chance, on the other hand, that it might never be found.
The show you mention was simply wrong. They only talked about the superficial things. Sure, skyscrapers would be gone. But the foundations of skyscrapers would only be gone if someone removed them.
Concerning a million years later, we have evidence for people more than a million years ago. Anyone a million years from now could find more evidence for these people, they'd just be two million years old by then.
All the evidence we have of our past survived the last Ice Age. We have found the remains of grass huts that were built on beaches (beaches) tens of thousands of years old. We have found wooden spears that are hundreds of thousands of years old.
Okay, it's possible we haven't found evidence for every civilization that ever existed, every culture that ever succeeded. But we've found enough to know there weren't any highly advanced ones in the past. If there were, why was everyone else making their tools by breaking rocks?
