Giant human skeletons

The claim

A race of human giants, three to four metres tall, once lived on Earth. Their skeletons have been found and hidden from the public.

No evidence

No giant human skeleton has been verified. The famous ones were faked.

The tallest verified person was 2.72 m. Famous “giant” discoveries are carvings, photos edited with software, or ordinary bones misjudged. Physics also limits how large a human body can be.

Short answer

The tallest person ever verified was Robert Wadlow, at 2.72 m, and he needed leg braces to walk [1]. The best-known giant discovery, the Cardiff Giant of 1869, was a gypsum statue buried by a hoaxer [3]. A widely shared photo of a giant skeleton was created for a 2002 Photoshop contest [5]. In the 1800s, newspapers reported giant skeletons in burial mounds, but the Smithsonian's survey of the mounds found ordinary human remains and no race of giants [6]. A real giant ape, Gigantopithecus, lived in Asia, but it was not human and is known mainly from teeth and jaws [4].

What supporters can show

Verified

Stories of giants appear in many traditions

Source
The Bible mentions the Nephilim and Goliath, Greek myth tells of the Titans, and many other cultures have stories of giants.
Shows
That giants are a common theme in folklore.
Does not show
That giants lived. Folklore is full of creatures that never existed.
Verified

Very tall people exist

Source
Robert Wadlow of Illinois grew to 2.72 m, the tallest person ever verified [1].
Shows
That human bodies can grow very tall.
Does not show
That an entire race could be that large. Wadlow's height was due to excess growth hormone, and his health problems and early death at 22 are documented [1].
Verified

A giant ape once lived

Source
Gigantopithecus was a very large ape that lived in Asia until a few hundred thousand years ago. It is known mainly from teeth and jaws [4].
Shows
That giant primates existed.
Does not show
That giant humans existed. Gigantopithecus was an ape, related to orangutans [4].
Partly verified

Newspapers reported giant skeletons

Source
In the 1800s American newspapers reported giant skeletons found in burial mounds [6].
Shows
That such reports were published.
Does not show
That they were accurate. The Bureau of Ethnology examined hundreds of mounds and reported that the builders were Native Americans [6].
Not verified

Photographs of giant skeletons circulate online

Source
Several photographs of enormous skeletons with workers standing beside them are widely shared online [5].
Shows
That the images are popular.
Does not show
That they are real. The best-known one was made for a Photoshop contest [5].
Could not verify

Claims that supporters often repeat and that we looked for but could not confirm in a reliable source.

  • The Smithsonian cover-up. A common claim is that the Smithsonian destroyed giant skeletons. We found no documentation of such skeletons or of their destruction.
  • Giant skeletons in caves and deserts. Stories repeated online, with no named excavation, date or museum holding the bones.

What science found

Human bodies cannot scale up

Galileo explained in 1638 that if an animal's body is made larger in all dimensions, its weight grows much faster than the strength of its bones [2]. A human of three to four metres would weigh several times more than an ordinary person, and the bones would have to be much thicker. Robert Wadlow, at 2.72 m, had trouble walking and died at 22 from an infection [1].

The Cardiff Giant was a hoax

In 1869 workers digging a well in Cardiff, New York, found a stone “giant”. It had been carved from gypsum and buried by the businessman George Hull. It was exposed as a hoax and Hull confessed [3].

The giant ape was not human

Gigantopithecus was a large ape known from teeth and jaws, not from a body, and it died out long before modern humans reached Asia [4]. Its jaw is much bigger than a human one but the animal does not resemble a giant person.

The famous photo was made in software

The image of a giant skeleton being dug up was submitted to a 2002 Photoshop contest on the website Worth1000, and later passed around as a real find [5].

The mound builders were ordinary people

The Smithsonian's survey of the burial mounds, published in 1894, showed the mounds were built by ancestors of Native American peoples and contained ordinary human remains [6].

What is still open

Whether any real, unusually tall prehistoric humans lived is a normal anthropology question, studied from real bones. The records give ordinary ranges of height [4].

If this happens to you

When you see a photo of a giant skeleton, do a reverse image search. Real finds have a named site, a museum and a published report. Edited images usually have none.
