The Kingdom of Yam definitely existed and is recorded as trading with the Old Kingdom of Egypt, but it’s physical location is as mysterious as Atlantis. According to one account, the Kingdom of Yam was a land of incense, ebony, leopard skins, elephant tusks and boomerangs. So where’s that?

Based on accounts of how long the journey was, as well as hieroglyphs found over 430 miles away from Egypt, across the Sahara Dessert, it seems like the Kingdom of Yam was in present day Chad. But here’s the thing; the wheel wasn’t invented yet, so Egyptians would have had to undertake a 7 month journey, with only donkeys as pack animals, to trade with this Kingdom. That’s hardcore.
