Why did they grow barley back in the bronze age?

In the Bronze Age, barley was widely cultivated due to its adaptability to various climates and soil conditions, making it a reliable crop for ancient farmers. It served as a staple food source, providing essential nutrients and energy for growing populations. Additionally, barley's versatility allowed it to be used for brewing beer, which played a significant role in social and religious practices. Its relatively short growing season also made it an attractive option for farmers in regions with shorter agricultural cycles.
