User aaaaaatttuyy has not mentioned the fact that NASA has recently found a crater under the Hiawatha glacier in Greenland that was, at the time of discovery, supposed to be 12k to 3M years old.
But a paper from March that tries to cross-validate this finding by looking at sedimentary data in South-America finds that the impact must have occurred 12,835 ~ 12,735 years ago.
And this, is what Graham Hancock has been supporting for so long. And yeah Semmelweis was full of himself as well.
Now to answer your questions about archeological sites:

- Underground city around the world: https://www.youtube.com/watch?v=zMjbtb4xLGQ&t=5s
- Underground city under the Giza plateau https://www.youtube.com/watch?v=BVR5V-cmpbA

- Underwater city off the coast of Cuba https://www.youtube.com/watch?v=JhcCjbl2Vjc
- Similarity between various archeological sites: https://www.youtube.com/watch?v=eYfpu2sHZuo
- The Antikythera Mechanism https://www.youtube.com/watch?v=hkL5Wkj1gYk
- The Ellora caves in India (as much work as the buildingof the great pyramid): https://www.youtube.com/watch?v=_WypT8RPUxg
- The "laser-cut" Lomas Rishi caves (India again): https://www.youtube.com/watch?v=ShObd9t_0Oc
- The fact the Giza pyramid and some megalithic structures around the world (some in Corsica for instance) are north-aligned with a greater precision than Copernic's observatory: https://www.youtube.com/watch?v=NDBA3fhCfmo
- The Sahara used to be green and turned into sand in a generation, around **11,000** years ago: https://www.smithsonianmag.com/science-nature/what-really-turned-sahara-desert-green-oasis-wasteland-180962668/
- The Great Pyramid could be a giant ram pump : https://www.youtube.com/watch?v=QDUwD59OYzI&t=122s
- The pyramids could be made of artificial re-agglomerated limestone : https://www.youtube.com/watch?v=znQk_yBHre4
- The Machu Pichu has not been built by the Incas and the walls were made out of molten stone.
- Organic matter in the incredible ruins of Puma Punku, Peru, show stones where made by pouring a geopolymer into casts: https://www.youtube.com/watch?v=0Q1f0YBm4ic&t=317s
- Etc ...
The list is long, and as you may have noticed, I tried to pick
short videos here. Also most of them are "crackpot" theories from youtube. It may be unbearable to watch if you like to razzor-cut bushes the Occam style. Now if you like to watch them grow into a passionately intricated puzzle and can enjoy these videos like a Netflix series, this might interest you.
A few channels/authors to follow on the matter:
- Graham Hancock
- Ancient Architects: https://www.youtube.com/channel/UCscI4NOggNSN-Si5QgErNCw. Both crackpot theories and scientific news related to the topic. Very prolific
- Bright Insight: https://www.youtube.com/channel/UCsIlJ9eYylZQcyfMOPNUz9w/videos. Similar, but more crackpot.
- Le Moment Curieux (french) : https://www.youtube.com/channel/UCyVPaIiBL9ieiyMeoCTR0SQ. Deep analysis of cyclopean/polygonal walls around the world + a toy-model of the Great Pyramid as a pump.
- Suspicious0bservers's Earth Catostrophe Cycle: https://www.youtube.com/watch?v=wvjJqIXYT1w&list=PLHSoxioQtwZfY2ISsNBzJ-aOZ3APVS8br most stars including the sun cyclically burst into "micro-nova" events and cause poles to shift. This is Roland Emmerich grade entertainment and very enjoyable. Very scientific as well altough a tad conspirationist.
- The science behind comet capture then disintegration in the solar system: https://cosmictusk.com/how_a_disintegrated_comet_destroyed_the_world/
But the best way to deep into the subject (warning, lot of numerology ahead!) is this documentary and its sequel:
- The Revelation of the Pyramids: https://www.youtube.com/watch?v=2fS9ixfQ_no&t=793s
- Builders of the Ancient World: https://www.youtube.com/watch?v=okhDDknJ9o0&list=PLt3D1556v66JLCCEtdI7spskIsvDUwylw&index=1
Thank you for your comments in this thread. I’m learning quite a bit from them!
