Then YHWH rained upon Sodom and upon Gomorrah brimstone and fire from YHWH out of heaven.

Genesis 19:24

As the Hebrews were a nomadic people, their lifestyle was much the same as when we go camping, and what camp is not complete without a fire. Not only is it used for camping, but a place where family and friends get together to tell stories, play music and just relax after a long day.
