the cave is where humanity learned to draw before it learned to write
means A natural hollow or chamber in the earth, typically in a hillside or cliff and often extending underground.
from From Latin 'cava,' meaning a hollow, from 'cavus,' "hollow, concave" — the same root that gives us 'cavity,' 'cavern,' and 'excavate.' It came into English through Old French 'cave.' The unrelated verb 'cave in' is murkier: possibly from a dialect word 'calve' meaning to collapse, later reshaped by association with the noun.
