The "Bible scholars" are saying it "might be" Sodom.
If Sodom is found, excuse me, but big whoop. Rome is also mentioned in the bible--another real city.
The melted stuff they found has plausible explanations within the natural universe (meteor shower). This further proves the fact that the Sodom story is one of many myths developed by pre-scientific people to explain things they didn't understand. If anything, this discovery reiterates the fact that the Bible contains myths.
