They talk about Sodom and nothing else. I've seen theories about specific sites and what happened to them, not so coincidentally in the same time period. The biggest issue with stories like this is that they look at 1 site and 1 site only. Not what's happening regionally to everyone at the same time. Although my timeline may be off, I can't remember exactly how close the alleged time of Sodom is in relation to the end of hte Bronze age, but...
. 3 major civilizations all surrounded the Mediterranean. You had the Hittites, Egypt, and Mesopotamia. They traded frequently, they had the best economies and strongest armies. 2 of the 3 completely disappeared, with Egypt barely surviving thanks to agriculture and breeding new forms of cows that were hardier. Once they connected all 3 of these and all the evidence, it became pretty obvious what happened. First, a drought that lasted at least 50 years. Soil samples prove it. The region is on multiple fault lines and there is a ton of evidence of split cliffs, ruins, monuments etc. that show the region was rocked by massive earthquakes. Volcanoes caused by the earthquakes likely added to it. To complete the trifecta, they had their own bought of smallpox that wiped out many. All of this, thanks to the plague, starvation, and disasters eventually led to a civil war of the poor revolting against the big dogs. These cities were destroyed both by natural disaster and war, wiped off the man, and covered by the sands of time. Maybe it's possible a cosmic impact triggered all of this.
