Caves and humans

Caves are naturally formed voids in rocks of such size that a person can enter them (crawl, squeeze in, but also run or climb up, seeing with difficulty their walls and ceilings in the light of even strong lamps).

It is a mysterious world of corridors, halls, vertical wells and rising chimneys, underground rivers and lakes; a world in which one can still be an explorer and set foot as the first man.
