Ancient world: they didn't have as many things to worry about like nowadays
Ancient times wasn't really worry free. There were still murders,rapes,wars,corrupted rulers ,etc just now what we worry must are advance weapons/technology. Such as nukes,drones or government spying on the people.
Here's some unsolved muders :
Shanidar 3
50,000 B.C.
-In the Zagros Mountains of Northern Iraq, archaeologists unearthed a Neanderthal murder victim. The specimen, named “Shanidar 3,” was a 40–50 year old and died of a puncture wound to his ninth rib. After testing Paleolithic weapons on goat and pig carcasses, experts determined a lightweight throwing spear caused the damage. Neanderthals had long, heavy stabbing spears, but they did not have projectile technology.
The prime suspect: a modern human. Was it a territorial dispute? An accidental encounter with fatal consequences? Or were the modern humans hungry? Evidence has emerged that modern man cannibalized Neanderthals. Tool marks on Neanderthal jawbones from Les Rois cave in southwestern France match those on slaughtered reindeer remains from the area.
Herxheim Cannibal
5,000 B.C
-Excavations in the German town of Herxheim gave us a window into the world of 7,000 years ago. They unearthed large structures, pottery, and victims of cannibalism. At least 10 individuals had cut and scrape marks indicative of butchering techniques. Some bones had chew marks. Others were deliberately smashed, as if to access marrow. Ribs were cut away from spine, muscles removed from head to allow access to skull cap, tongues cut out, flesh from limbs removed. There were two distinct types of marks—skinning cuts, and deeper cuts to access meat. There is no evidence whether they were cooked or eaten raw—although markings on remains suggest spit roasting.
Moche Massacre
A.D. 150–750
-In the arid lowlands of Northern Peru, archaeologists unearthed a grave complex from the Moche civilization, containing over 100 victims of brutal deaths. Their skeletal remains reflect a smorgasbord of terror. They were skinned alive, drained of blood, decapitated, or bound and left for the vultures. All the victims were young men, cast into open pits, alone or in small groups. The Moche came before the Incas. Moche civilization thrived in the arid valleys of Peru, in A.D. 150–750. They were advanced builders, artists with irrigation techniques that made their land even more fertile than modern techniques.
So is ancient times peaceful? No.
If humanity dies, how will there be peace? Also how does the ancient world bring peace? Explain guys above me
Peace is freedom from fear of violence. If humanity dies then there won't be peace cause no humans are alive to fear violence. But from any other animals prospective towards humans, they fear us cause we destroy their home by chopping down trees,etc. So for them,there's peace.
Though most animals will kill for territory,food,etc
