Hancock often suggests that evidence points to a civilization existing around 12,800 years ago, at the end of the last Ice Age. The hypothesis relies heavily on the Younger Dryas period—a time of abrupt climate change characterized by rapid sea level rise and widespread environmental upheaval. While the Younger Dryas is well-studied, any claims about megastructures predating this period require exceedingly compelling evidence, such as cultural layers, material artifacts, physical structures, or genetic data linking populations across vast distances.
