Did anyone see that documentary on TV recently (about a year ago i think) that was called something like 'If humans disappeared tomorrow' or
similar?...it was a good programme that posed the question, how much evidence of humanity would remain, and how long would it remain, if humanity
suddenly went the way of the Dodo.
If i remember rightly, the vast majority of our buildings, roads, tracks and so on would crumble, rot and be gone in as little 500 years.
There would be evidence left in the form of certain plastics and composite items, but these too would crumble away in about 5000 years.
So really, apart from jewellery items, and things like that, if future archaeologists in say 20,000 years were digging for evidence of our current
generations, they'd find virtually nothing..coins, jewellery, certain industrial items made from gold, diamond, and so on might be found, certainly
no structures, computers, ipods, mobile phones, cars, aircraft, etc.
Unless a city was completely buried and preserved in an oxygen free environment, like from silt due to a mega tsunami, or tidal wave and layered over
(as this wall may have been) by millennia of sediments and Earth, nothing much would remain to show we were ever here.
They might find some jewellery, or gold/silver coins etc, but probably would not conclude we were highly advanced technologically, as no evidence of
complex machinery or the ability to fly in aircraft, sailing in mighty ships, travelling to space, complex electronics would remain.
They would probably credit us with a society similar to how we view 20,000 year old human archaeological finds today.
If this wall had not been layered over by the organic material and silts that eventually became compressed coal, it too would probably have eroded and
disappeared.
Anyone fancy Organising an ATS expedition to the mine for some investigation work?
You USA members could organise a local expedition (group together for discounted travel and lodging, or camp under canvas, etc), and report back to us
in the rest of the members in the world too poor to afford the travel cost (

)
It would be an interesting trip i'd imagine.
