When was the first gun created?
user
The first gun was invented by the Chinese. Their discovery of gunpowder was some 1,400 years ago. They may have had some small cannons for long-range fire, but the first “gun” was a hand-held weapon for close-range use. There are lots of illustrations and engravings showing these weapons, and I have some pictures and a written description here.  You can see some here.

When was the first machine gun invented?
user
The first machine gun was developed by a German, Friedrich von Mauser, in 1874. A machine gun is a weapon that fires continuously, by hand-cranking the ammunition into the chamber. This means that one person can fire several bullets per minute. A muzzle-loader is a gun that needs to be loaded one bullet at a time. Here’s a Wikipedia page about the first machine gun.

When was the first machine gun invented?
user
The first machine gun was invented by Richard Jordan Gatling in 1862. You can read about it here. Gatling also created other weapons that used the recoil of a gun to propel another projectile, and he improved the hand-cannon. These include a Gatling gun, a shotgun that worked on the same principle, a cannon, and several shotguns.
