You know you might have a point in terms of gold and silver bullion if it's buried and relatively undisturbed for 10 000 years.
Apart from that what else? Stainless steel lasts a lifetime, not 10 000 years. You might be right I'm just curious.
In humanities case,
The Pyramids themselves could last hundreds of thousands of years
Geosynchronous satellites will hang around near indefinitely (and our lunar lander and other stuff left behind on the moon)
There could be evidence or clues of all our mining operations
The sediment record could leave clues that an industrial civilization once existed for millions of years
We dig up dinosaur bones that are hundreds of millions of years old. Maybe our own bones might be discovered someday. We certainly haven't dug up any fossils that look like they belonged to an advanced civilization though or maybe they were soft bodied
Yeah I concede the lunar lander.
The Pyramids are stone.
This will blow your mind. This is pearls before swine and it is mine, but you can have it for free.
If the universe is infinite, which is a popular theory, there is an infinite chance of this exact situation happening somewhere else in the universe.
Every single detail, down to quantum fluctuations, there is an infinite chance that it is currently happening somewhere else, right now, as I am writing this post.
As humans we don't have the mental prerequisites to understand infinity.
