How Natural Disasters Can Erase Human Settlements
This visual comparison highlights the vulnerability of human infrastructure to geological events. The top frame shows an aerial view of a landscape marked by a significant landslide or debris flow, while the bottom frame provides a satellite perspective of a built-up area situated in a river valley. The juxtaposition suggests how natural processes, such as landslides and erosion, can rapidly alter or completely bury human settlements, potentially explaining why evidence of ancient civilizations from tens of thousands of years ago is difficult to recover. The imagery serves as a reminder of the powerful, ongoing forces that reshape the Earth's surface and the challenges of preserving human history against such environmental changes.

Last ice age started 115,000 years ago. There were nearly any humans let alone cities at that time.
Humans were around, but certainly weren't building anything we would call the city, even town, back then.
Explains literally nothing
We find imprints of old structers which eroded away after thousands of years and they think it was machine cut
There's other more obvious reasons why you can't find cities older thank 100 thousand years.
Too soon?
Only megalithic structures remain
Missed a couple of history lessons OP ?
1. Landslides doesn't happen all around the world, and people don't build settlements only in the mountains 2. Last ice age lasted ~115k years 3. People back then didn't had technology to build anything durable, to stay intact till this day (even as a ruins)
I feel like there is a lot of context, but I am missing the necessary mind altering items.
