Which country was the earliest weapon?

Stone sticks used by people in primitive society for hunting can be considered as the most primitive weapons, because they have the characteristics of weapons: the user's operation causes the other person to be injured or killed, so as to achieve the user's expected purpose.

But I think it is wrong to say that archers are the earliest weapons. It should be said that bows and arrows are the earliest long-range weapons.

It can be said that the country where primitive humans first appeared was the country where weapons first appeared.

From 1974 to 1975, archaeologists discovered early human remains more than 3 million years ago on the banks of the Gallus River in northern Tanzania. This discovery caused a sensation in the world.

13 early human skeleton fossils were found on both sides of the Garuxi River, mainly including maxilla, mandible and teeth. According to the determination, its age is about 3.77 million to 3.59 million years ago, belonging to early apes. This is the earliest known human fossil.

So it can be said that Tanzania is the first country to use weapons in the world.
