The discoveries are speeding up. There seems to be good evidence that the same type of megalithic structures were built in various places (Peru, Egypt, Turkey) around the world around 12,000 years BC. The builders were remarkable engineers, were able to move 200 ton blocks of granite and join them without any adhesive, and they seemed remarkably uniform in their approach to design. The emerging consensus is that these civilizations were wiped out by a massive flood, perhaps sparked by a comet or asteroid strike.

Do you have links to that ‘good evidence’?
Thx.
What discoveries????
And there isn’t any evidence of these structures even under the pyramids and definitely not in Peru.
in Turkey or rather eastern Turkey, near the place where wheat originated, we have Gobekli Tepe, but no great megalithic structures like the Ancient aliens theorists propose. Gobekli Tepes is dated to approximately 9,500 BCE (about 11,500 years ago), with construction spanning into the 8th millennium BCE. It’s a ceremonial site with circular enclosures and T-shaped limestone pillars, built during the Pre-Pottery Neolithic period. While it predates known agriculture and settled civilizations, it’s slightly later than the 12,000 BCE mark and shows no direct links to sites elsewhere.
In Peru, the oldest megalithic structure —> Callacpuma (a circular stone plaza in the Cajamarca Basin) dates to around 2,750 BC — not 12,000 BC
In egypt, the oldest structures are Nabta Playa in the Western Desert, with stone alignments and cattle burials from around 7,000–6,000 BC.
While Göbekli Tepe is genuinely ancient and revolutionary (proving complex societies existed before farming), there’s no evidence for similar structures in Peru or Egypt at that time.
The Younger Dryas Impact Hypothesis (YDIH), which posits a comet airburst or impact ~12,900 years ago caused global cooling, floods from melting ice sheets, megafauna extinctions, and the collapse of early human societies is widely rejected by geologists, climatologists, and archaeologists.. WHY?
1. Proposed evidence (e.g., nanodiamonds, microspherules, iridium layers) is inconsistent, non-reproducible, and explainable by terrestrial processes like wildfires, volcanism, or contamination.
2., No impact craters from that period; dates of supposed markers vary widely (14,000–10,000 years ago)
3. Megafauna extinctions were asynchronous (e.g., North America ~13,000 years ago, South America later) and better explained by human overhunting and climate change.
If such a society existed, traces like tools, metals, writings, or widespread debris would remain—none have been found despite extensive searches. Göbekli Tepe’s builders survived into later periods, with no evidence of flood destruction.
These claims you cite rely on “arguments from ignorance” (e.g., can’t explain it, so aliens/comets”)
