proof that humans, faced with a mountain, would rather dig than walk around
means Tunnels are passages dug or bored through the ground, a hill, or beneath water to let people, vehicles, or trains pass through what would otherwise block the way.
from From 'tunnel,' which came into English from Old French 'tonnelle,' a cask or barrel — itself a diminutive of 'tonne,' a tun or large barrel. The word first meant a tube-shaped net or a funnel, then any pipe or shaft, before settling on the hollow passage we mean today. So a tunnel is, etymologically, a kind of stretched-out barrel you walk through — the shape of a cask handed down to the shape of a hole in a mountain.
