- Graham Hancock believes a superior civilization was destroyed by a comet 12,000 years ago, leaving few traces.
- Critics argue that a devastating impact wouldn't erase all evidence like tools, writing, or trash.
- The comet impact theory, linked to megafaunal extinction, lacks craters and has inconsistent radiocarbon dating.
- Hancock's reasoning relies on arguments from ignorance and personal incredulity, similar to 'God of the gaps' logic.
- Göbekli Tepe is cited as evidence, but its ceremonial use and hunter-gatherer context don't prove a high civilization.
- Decades of searching haven't convinced archaeologists to revise human history timelines.
- Catastrophism is accepted in science, but Hancock's specific claims lack sufficient evidence.
