Answer 1

Caves are protected environments. No wind, no water, few animals. The cave drawings that survive are generally in very isolated , deep parts of caves where’s there even less of those factors.

Prehistoric people probably drew lots more stuff in lots more places, but those places would be more affected by erosion, weather, animals, and later populations
