Archaeological evidence shows that ancient civilizations that developed writing systems subsequently experienced rapid advances in mathematics, astronomy, and architecture. The Sumerians invented cuneiform writing around 3200 BCE, and within centuries had developed sophisticated mathematical concepts and monumental architecture. Similarly, the Maya created their writing system and then made remarkable astronomical calculations. The Egyptians followed the same pattern with hieroglyphics preceding their architectural achievements. It is clear, therefore, that developing a writing system is necessary for a civilization to make significant advances in science and technology. Modern developing nations should prioritise literacy programmes, as without widespread writing ability, they cannot achieve technological progress.
