There’s been a recent wave in the email circulation of archaeological evidence for giants, usually with a tagline that this is proof of the Bible’s accuracy.
I might suggest a simple principle for dealing with matters like this in the future: if you heard about it first in an email forward, it’s not true.
Indeed, these photographs were created for a contest for images of an archaeological hoax. These came in third place in a 2002 competition.
Circulation of the images as “real” apparently began in 2004. National Geographic debunked them in 2007. PaleoBabble posted on them in February. Truth or Fiction has a full copy of the email that I’ve been forwarded many times now.
