How does Tyler Engle read ancient temples and pyramids? Show answer

As a system of geometric and acoustic technology meant to shape the environment and human consciousness, though he admits the process isn't fully worked out.

What part of Engle's view does he consider testable? Show answer

Sound and geometry, such as the long reverberation in carved stone chambers. Many of his other mechanisms remain unproven by his own account.

What is Graham Hancock's hypothesis? Show answer

That an Ice Age civilization was largely destroyed around 12,800 years ago and its survivors passed on knowledge. He says he is not claiming to have proved it.

Why does Hancock call Göbekli Tepe a game changer? Show answer

Its megalithic enclosure dates to about 11,600 years ago, thousands of years older than the previous oldest megalithic site, and appears among hunter-foragers.

What does Hancock mean by an advanced lost civilization? Show answer

Not something like us. He agrees it may have been a relatively small group of star scholars and expert seafaring navigators.

What is the Younger Dryas in Hancock's account? Show answer

A sudden return to Ice Age cold about 12,800 years ago, lasting until about 11,600 years ago. He says the proposed comet impact behind it remains a hypothesis.

How does Ed Barnhart explain why pyramids appear in many places? Show answer

Without rebar or cement, anything big and tall needs a fat base and skinny top. Monuments also answer a shared human fear of death.

What does Barnhart think the first Peruvian pyramids were? Show answer

Trash management: piles of fish waste capped with dirt and clay that later became mounds and sacred places.

What is Barnhart's controversial idea about Andean religion? Show answer

That one creator deity with goggle eyes, fangs and snakes runs through it, from Chavin through later cultures to the Inca's Viracocha.

Why does Barnhart reject Hancock's lost civilization? Show answer

Archaeologists find even fish scales, so an advanced global civilization leaving not a single potsherd is too much to accept. He sees independent development.

What do all three guests agree on? Show answer

That the record of the past is incomplete, that altered states mattered to early religion, and that flood stories reflect real events.

What is Barnhart's own unproven hypothesis about Inca walls? Show answer

That the builders used acids, made from mining byproducts and fluorite, to produce the seamless joints. He wants core samples to test it.

This is the short form. The full insight has every expert's reasoning, their own words and the sources.
