New Defender's Study Bible Notes
4:22 brass and iron. Evolutionary archaeologists have attempted to organize human history in terms of various supposed “ages”–Stone Age, Bronze Age, Iron Age, etc. The Noahic record, however, indicates that early men were very competent in brass and iron metallurgy, as well as agriculture, animal husbandry, and urbanization. It is significant that both many kinds of bronze and iron implements are known to have been used in the earliest civilizations of Sumeria and Egypt. The same is true of musical instruments, and it is evident that the science and art of both metallurgy and music, as well as agriculture and animal husbandry, had been handed down from ancient times to these earliest post-Flood civilizations. Modern archaeology is confirming the high degree of technology associated with the earliest human settlers all over the world.
