2012 is based on a spec script (speculative script) co-written by director Roland Emmerich & co-producer Harald Kloser, indicating in the the end credits that the film was "inspired in part" by the book Fingerprints of the Gods by Graham Hancock. The film borrows several themes and elements from Jules Verne's rarely known novelette "The Eternal Adam", which shows a distant future archaeologist called Sofr-Ai-Sr, who belongs to a completely different civilization from ours called Hars-Iten-Schu, and someday finds a manuscript inside an aluminum box, narrating how in May 24th, 2XXX, a limousine driver called Modesto Simonet, his scientific boss (who wrote the manuscript), other scientifics on a vacation, and several other notable men and their families in Rosario, Mexico, survived a sudden flooding from the Atlantic Ocean by the heroic act of Simonet, who drove a car as fast as he could towards the mountains. In a matter of hours, the whole American Continent sinks in the ocean, except for the small island that used to be a mountain. They are rescued by a cargo ship, and they wander in a futile search for land anywhere else, only to discover that the tiny island was growing every time they passed by. The manuscript author ponders on the fate of Atlantis, and points a parallel with his situation. This old document leads Sofr to think that his civilization is descendant from those survivors after a period of mass involution of the human race, and that they survived thanks to a whole new continent that raised from the bottom of what used to be the Pacific Ocean for the survivors, and for Sofr is the only existing continent. Also, Sofr theorizes that is imminent that another global flooding happens someday. While the movie is far from an adapted work, a small credit would have been used instead of that of Graham Hancock, given the obvious allusions, but the reason why it wasn't the case is not known by the public.
