Skeptoid #1014: The Giant of Kandahar

November 11, 2025

Key Takeaways Copied to clipboard!

  • The story of the Giant of Kandahar, which claims US Special Forces fought a massive humanoid in Afghanistan, originated with author Stephen Quayle on the radio show Coast2Coast AM in 2005, likely as promotion for his book. 
  • The physical plausibility of such a giant is severely limited by the square-cube law, which dictates that a creature twice the height of a man would require 27 times the strength to support its weight, making the reported size and agility biologically impossible without extreme, unobserved structural changes. 
  • Despite later viral videos and anonymous claims of eyewitnesses, the Department of Defense has no record of the incident, and the narrative's origin points directly to self-published fiction promoted on paranormal radio programs known for lax journalistic standards.

  • Key Takeaway: The popular narrative describes a firefight with a 13-foot-tall, red-haired giant wielding a spear, which was eventually killed by M4 and .50-caliber rounds.
  • Summary: The story posits that US Special Forces encountered a giant, described as two to three times the height of a man, armed with a spear. The creature reportedly killed a soldier named Dan before being killed itself after sustaining heavy gunfire. The body was allegedly taken into US military possession.
Tracing the Story’s Popularization

  • Key Takeaway: Filmmaker L.A. Marzuli significantly boosted the story’s visibility in 2016 by linking the giant to the biblical Nephilim.
  • Summary: The story gained traction after L.A. Marzuli’s 2016 video linked the Kandahar giant to the Nephilim mentioned in the Bible. Marzuli cited an anonymous driver and an anonymous caller on the Dr. J radio show as supposed sources. Details in various accounts often change regarding military branch and corpse removal.
Scientific Analysis of Giant Proportions

  • Key Takeaway: Scaling a human body up requires increasing thickness by the square root of the scaling factor to maintain structural integrity, leading to a weight increase proportional to the scaling factor raised to the fourth power.
  • Summary: The square-cube law must be modified for biological organisms by adding a stockiness factor (the square root of the scaling factor). This means weight scales to the fourth power, not the third, to maintain structural strength equivalent to a normal-sized organism. Robert Wadlow, the tallest human on record, demonstrated the fragility of scaling height without proportional robustness, suffering severe physical impairments.
Identifying the Story’s Originator

(00:09:33)
  • Key Takeaway: All narrative threads trace back to Stephen Quayle’s appearance on Coast2Coast AM in November 2005, where he promoted his book on giants.
  • Summary: The investigation traces the story back to Stephen Quayle’s radio appearance on Coast2Coast AM on November 7, 2005. Quayle, an author publishing through End Time Thunder Publishers, claimed an Air Force pilot told him the story. This initial telling estimated the giant’s weight at 1,100 pounds, which mathematically limits its height to about 9 feet 2 inches, contradicting the ’twice as big’ claim.
Promotion and Due Diligence Failures

(00:15:28)
  • Key Takeaway: Quayle’s initial radio appearance coincided with the release of his fiction novel, Longwalkers: The Return of the Nephilim, suggesting the story was promotional material.
  • Summary: Quayle appeared on Coast to Coast AM again in 2008 to promote a second edition of his novel, bringing an anonymous alleged pilot guest. The show is noted for its lax due diligence, having previously broadcast interviews with fictional characters like Dr. Gordon Freeman from the Half-Life video game. The Skeptoid episode concludes the Giant of Kandahar is the fictional invention of Quayle promoting his work.
