A massive comet explosion that rocked Louisiana nearly 13,000 years ago has provided new evidence supporting one of archaeology’s most controversial theories. The discovery of a 984-foot-long crater-like depression, caused by a cosmic airburst equivalent to thousands of nuclear bombs, adds to the argument that an advanced civilization once flourished on Earth before being catastrophically destroyed. This latest finding brings author Graham Hancock’s theories about a lost Ice Age civilization back into the scientific spotlight, challenging mainstream archaeological narratives about humanity’s past.
