Randall Carlson, the Younger Dryas, and the science behind catastrophic climate shifts.

In this episode of The Lost Civilizations, we examine Randall Carlson’s views on catastrophism, cyclical risk windows, and the controversial Younger Dryas Impact Hypothesis. Often associated with Ancient Aliens, Carlson does not argue for extraterrestrial intervention. Instead, he explores whether Earth’s history includes abrupt climate shifts, megafloods, and possible cosmic events that reshaped early human civilization.

We review the evidence for and against the impact hypothesis, including platinum anomalies, proposed impact markers, and competing explanations such as disruption of the Atlantic Meridional Overturning Circulation (AMOC). We also explore why complex, interdisciplinary ideas are frequently polarized or misrepresented in public discourse.

Are catastrophic events cyclical? Is this about probability or prophecy? And how should we approach scientific uncertainty without collapsing into speculation?

This episode examines geology, climate history, and the politics of complexity — not apocalypse narratives.

Across the world, archaeologists have uncovered vast underground cities capable of sustaining thousands of people for long periods of time. These are not simple shelters or temporary hideouts, but complex systems with ventilation, water management, storage, and social infrastructure—built with long-term survival in mind.

In this episode, we explore why ancient societies invested so heavily in building beneath the surface, and why these structures are often treated as anomalies rather than part of a global pattern. Was the threat war, climate instability, repeated environmental crises—or something even more unpredictable?

We examine archaeology’s blind spots, the limits of siloed research, and why “refuge” is an incomplete explanation unless we ask what people were repeatedly seeking refuge from. From climate shocks to rare cosmic events, this episode reframes underground cities as a form of long-term risk management.

This is not an episode with easy answers—but with better questions about resilience, planning, and how civilizations survive uncertainty.

For decades, military and civilian pilots reported encounters they could not explain — and learned quickly that speaking up came at a price. This episode examines what happened to those who challenged the established narrative long before 2017, when the conversation around UAPs suddenly changed.

Focusing on documented cases involving U.S. Navy pilots, this episode explores how professional credibility, career advancement, and institutional culture shaped what pilots were willing to report — and what they chose to keep quiet. Rather than censorship, the system relied on stigma, humor, and silent consequences to discourage discussion.

By tracing pilot testimonies, historical programs like Project Blue Book, and the sudden shift in official language after 2017, this episode reveals how silence can be manufactured without force.

This is not an episode about proving what UAPs are.

It’s about understanding what happens to truth when speaking is risky — and why the absence of reports is not evidence that nothing was there.
