A stone wall acts as the monitor screen with a keyboard underneath it appeared in prehistoric times

The stone wall, a symbol of permanence, strength, and ancient craftsmanship, serves as the "monitor screen" in this scenario. Unlike our modern, sleek screens, a stone wall is rough, textured, and unyielding, representing the raw, unrefined nature of prehistoric life. Yet, by assigning it the role of a monitor, it suggests that even in prehistoric times, there might have been a form of "display" or a way of conveying information, albeit in a more primitive, symbolic form—perhaps through cave paintings, carvings, or other means of storytelling.

The keyboard, an object firmly rooted in modern times, further adds to the anachronism. Its presence beneath the stone wall could imply a bridge between the ancient and the modern, suggesting that the essence of human communication and the desire to record, share, and process information has always existed, evolving over millennia.
