Blending mythology, colonial-era science, and cultural pride, the episode explores whether Kumari Kandam was a real prehistoric land lost to rising seas or a symbolic memory preserved in ancient poetry. While geology disputes the existence of a sunken supercontinent, submerged archaeological sites off India’s coast suggest that real flood events may underlie the legend.
