The Paleolithic era likely featured abundant rock art beyond caves, illustrating early human creativity and communication. Unfortunately, much of this open-air artwork has been lost due to weathering and erosion. Remaining sites, like those in the Coa Valley, reveal a glimpse of what once existed, suggesting a vibrant, artistic society. If more had survived, our understanding of prehistoric people would be richer, showcasing art as a vital part of daily life. This loss highlights the transient nature of human expression and its enduring significance despite impermanence.
