Bab 493: Chapter 490: There is only one truth!

"The Stone Age began about 2.5 million years ago and lasted until approximately 7000 to 2000 years ago."

"From monkeys, we learned to throw stones, and by the time of the apemen, we were already using stone axes."

"The Bronze Age first started in the Mesopotamian civilization in the 4th millennium BC."

"In Huaxia, the earliest unearthed bronze artifacts are the small bronze knives from the Gan-Su Majiayao culture, which date back to around 2800 BC. My history isn't great, but that was probably the early Shang Dynasty, right?"

"In Ancient Egypt, bronze vessels appeared during the Second Dynasty, ushering in the Bronze Age."

"The Aegean civilization existed during the same period."

"And then, we have the Iron Age, which continues to this day."

"The ancient Egyptians and Sumerians were the first known to use iron tools, as early as 4000 BC, but mostly they obtained iron from meteorites rather than extracting it from iron ore, which made it many times more expensive than gold."
