Lost Civilizations

The discussion highlights the dramatic impact of glacial cycles on human habitation, particularly the erasure of evidence due to rising sea levels. Both Randall and Graham emphasize the need for a focused exploration of submerged lands, which could reveal civilizations that existed before the last ice age. They stress the importance of marine archaeology in uncovering these lost histories, challenging the prevailing archaeological biases that overlook pre-12,000-year-old civilizations.
