The history of bread dates back thousands of years, with evidence of its existence dating as far back as 30, 000 years ago. The earliest forms were likely simple flatbreads made from crushed grains and water, cooked on hot stones. As agriculture developed, people began cultivating grains like wheat and barley, leading to more sophisticated bread-making techniques. Ancient Egyptians are credited with refining bread-making by inventing leavened bread around 4000 BCE using yeast. From there, bread became a staple food in many cultures, evolving into the diverse varieties we enjoy today.
