Was Christopher Columbus a hero, a villain, or something farmore complicated? On Columbus Day 2026, Dave Bowman challenges the popularmythology surrounding the voyage of 1492 and asks whether modern culture hasforgotten how to recognize human achievement without ignoring human failure.

Columbus didn't prove the Earth was round. EducatedEuropeans already knew that. His mathematics weren't necessarily as foolish aspopular accounts suggest, and he wasn't the first European to reach theAmericas. Yet his voyage aboard the Niña, Pinta, and SantaMaría helped transform world history.

On this episode of Plausibly Live: The Dave Bowman Show,Dave examines the real history of Christopher Columbus, the nineteenth-centuryorigins of the flat-earth myth, the extraordinary navigational challenges ofcrossing the Atlantic, and the darker legacy of conquest and colonization.

Why has Columbus become such a controversial figure whileconquistadors such as Hernán Cortés and Francisco Pizarro occupy a differentplace in American public memory? Would someone else inevitably have sailedwest? And can we recognize Columbus's courage and seamanship whileacknowledging the suffering associated with his expeditions?

For Dave, a veteran submariner, the experience of going tosea offers a particular appreciation for the determination required to venturebeyond the familiar horizon.

Also in this episode: The Search for Noah's Ark

New reports from eastern Turkey have revived interest in theDurupınar formation near Mount Ararat. Researchers have reported unusualsubsurface patterns, soil chemistry, and other features that some believewarrant further investigation.

But what would actually constitute archaeological proof thatNoah's Ark had been discovered? Could such a discovery be scientificallyestablished? And would finding the Ark change anyone's religious faith?

Dave considers the distinction between archaeologicalevidence, historical interpretation, and religious belief, including his ownconviction that faith does not require the physical discovery of Noah's Ark.

From Christopher Columbus and the Age of Exploration to themountains of Ararat, today's episode explores the human desire to discover whatlies beyond the horizon and the difficult questions that follow.
