Geological markers like iridium and impact-related materials, which are expected from such an event, are either inconsistently found or disputed in terms of their origin.
The Younger Dryas Impact Hypothesis, which suggests a comet or asteroid struck the Earth around 12,800 years ago, causing massive climate change, remains highly controversial, where many scientists argue that there is insufficient evidence of such an impact.
Hancock emphasizes that many areas, particularly in remote or underwater locations, the Sahara desert and the Amazon have not been systematically investigated. This lack of exploration leaves open the possibility that evidence of advanced civilizations could still be discovered.
There is no conclusive archaeological proof of the existence of a highly advanced Stone Age civilization, as most of Hancock's claims are speculative.
Global megalithic structures, like pyramids and ancient temples, share architectural similarities that imply the existence of a shared, ancient cultural influence.
Ancient maps, like the Piri Reis map, depict detailed coastlines, potentially including Antarctica, long before modern cartography, implying advanced geographical knowledge.
The Younger Dryas Impact Hypothesis proposes a comet strike around 12,000 years ago, which aligns with Hancock's timeline of a global catastrophe wiping out an advanced civilization.
