"Ancient Aliens" with David Anderson—S2 Bonus Interview

Wild Thing is a long-form, narrative podcast about the obsessions that capture our imaginations. This sound-rich and deeply reported show examines the relationship between science and society—that point where scientific inquiry collides with our very human desire to find answers, even when there are none. Whether it's seeking out Sasquatch, looking skyward for extraterrestrial life, or probing the power of the atom, exploring the unknown helps us better understand ourselves. Every season, host Laura Krantz tackles a brand new topic, so be sure to start with the first episode for each one.
