Obviously, Bronze Age nomadic tribesmen were aware of the sulfur nodules (which may have been more plentiful or accessible / nearer the surface, etc. three thousand years ago), knew that sulfur is flammable, and hence concocted a crazy story about how they got there.
For modern people to then point to the nodules as evidence supporting their claim of divine retribution is in any case fallacious.

Your modernity is a Texas sharpshooter fallacy.
