These are real dangers, and they are dangers that have claimed the lives of cavers in the modern era, with all the equipment and safety awareness that modern caving brings to the activity.

For an ancient person, operating with a torch that could be extinguished by falling, by a sudden air current, or simply by burning out, the risks were if anything greater.

The accidental death hypothesis does not require that the man entered the cave with any intention of dying there.

He may have been exploring, or prospecting for resources — minerals, water sources, shelter, or other features that a cave might provide — when something went wrong.

An injury, a moment of disorientation, a lost torch, and the cave became the place he died rather than a place he visited and left.
