The historical existence of Sodom and Gomorrah is still in dispute by archaeologists. The Bible indicates they were located near the Dead Sea (Templat:Bibleverse-lb, Templat:Bibleverse-lb, Templat:Bibleverse-lb).

Strabo states that locals living near Moasada (as opposed to Masada) say that "there were once thirteen inhabited cities in that region of which Sodom was the metropolis". Strabo identifies a limestone and salt hill at the southwestern tip of the Dead Sea, and Kharbet Usdum ruins nearby as the site of biblical Sodom.[5].

Archibald Sayce translated an Akkadian poem describing cities that were destroyed in a rain of fire, written from the view of a person who escaped the destruction, however the names of the cities are not given.[6]. However, Sayce later mentions that the story more closely resembles the doom of Sennacherib's host[7].

The name “Sodom” is probably related to the Arabic sadama meaning 'fasten,' 'fortify,' 'strengthen' and Gomorrah is based on the root gh m r which means 'be deep,' 'copious (water)'.[8]

In 1976 Giovanni Pettinato claimed that a cuneiform tablet that had been found in the newly discovered library at Ebla contained the names of all five of the Cities of the Plain (Sodom, Gomorrah, Admah, Zeboim, and Bela), listed in the same order as in Genesis. The names si-da-mu [TM.76.G.524] and ì-ma-ar [TM.75.G.1570 and TM.75.G.2233] were identified as representing Sodom and Gomorrah, which gained some acceptance at the time.[9] However, Alfonso Archi states that, judging from the surrounding city names in the cuneiform list, si-da-mu lies in northern Syria and not near the Dead Sea, and ì-ma-ar is a variant of ì-mar, known to represent Emar, an ancient city located near Ebla.[10] William Shea points out in 1983 that on the 'Eblaite Geographical Atlas' [TM.75.G.2231], ad-mu-ut and sa-dam are good readings by Pettinato and correspond to Admah and Sodom, and they are contained in a list of cities that traces a route along the shores of, or quite possibly within the Dead Sea, whose position may have since shifted along its fault.[11] Today, the scientific consensus is reported as being that "Ebla has no bearing on ... Sodom and Gomorra"[12]

The cities may have been destroyed as the result of a natural cataclysm. Geologists have confirmed that no volcanic activity occurred within the last 4000 years, but it is possible that the towns were destroyed by an earthquake in the region, especially if the towns lie along a major fault, the Jordan Rift Valley, the northernmost extension of the Great Rift Valley of the Red Sea and East Africa.[13]

Possible candidates for Sodom or Gomorrah are the sites discovered or visited by Walter E. Rast and R. Thomas Schaub in 1973, including Bab edh-Dhra, which was originally excavated in 1965 by archaeologist Paul Lapp, only to have his work continued by Rast and Schaub following his death by accidental drowning in the waters off of Cyprus in 1970. Other possibilities also include Numeira, es-Safi, Feifeh and Khanazir, which were also visited by Schaub and Rast. All sites were located near the Dead Sea, with evidence of burning and traces of sulfur[14] on many of the stones and a sudden stop of inhabitation towards the end of the Early Bronze Age.[perlu rujukan] Archaeological remains excavated from Bab edh-Dhra are currently displayed in Karak Archaeological Museum (Karak Castle) and Amman Citadel Museum.
