For the most part, we look back to the religious practices of the past, and even those still practiced today with a raised eyebrow, to a disgusting sense of moral disgust. In the scientific literature, it is fairly well documented that human beings act as a last resort by attempting to assert their claim to social status, or simply by trying to give it away to the proposed supernatural powers that have been perpetrating people's lives Seek blessing and happiness to please. Here are 10 civilizations that participated in one of the strangest religious practices of all time, the victim of children.
Babylon, which was dead center in the birthplace of civilization, was a megalithic settlement and one of the most powerful forces of antiquity. They sacrificed the people of their chief deity, Marduk, as well as other persons such as Anu, a deity of the city of Uruk, in the later years of the Babylonian Empire. Annual refractories were held to sacrifice Anu children.
It is safe to say that human sacrifices were a staple throughout Babylon's entire existence, with the city's existence dating back to the 23rd century BC. Was mentioned for the first time. It sometimes remained a mighty city and a rich empire, until in 331 BC. By Alexander the Great was conquered. After that it could never quite regain its old splendor. 
The Aztecs are probably the best-known society because they sacrifice human beings for religious reasons. In October 2017, archaeologists discovered a rare find, a cylindrical pit that was excavated and lined centuries ago for the victims of the gods of the Aztecs with volcanic rocks.
Tenochtitlan was an ancient Aztec city now located in the heart of Mexico City. The find came at the foot of Templo Mayor, an Aztec temple in Tenochtitlan. It is believed that this child, known as Offer 176, was sacrificed sometime in the 1400s.
This was a time of Aztec expansion when many children were sacrificed to their gods. Most likely, 176 victims were killed to appease the Aztec god of war, Huitzilopochtli, and favor the city's residents. 
Canaan is the all-embracing term for the land that was in present-day Lebanon, Syria, Jordan and Israel. The Bible contains numerous references to an ancient Canaanite god named Molech (aka Moloch), for whom human sacrifice was both the norm and seemingly abundant.
Molech was even referred to by some as the "god of child sacrifice". It was believed that this deity was very content with offers that burned living people, especially children, in a fire.
In the Scriptures, the book Leviticus forbids this practice even. Leviticus 18:21 says, "Do not give any of your progeny to offer them Molech, nor profane the name of your God. I am the Lord. 
Before the Leviticus decree, the Israelites often practiced human sacrifice, including children, sometimes even the alien god Baal. We find other writings, such as those in Kings, which claim that the Israelites worshiped false gods and participated in the ritual killing of human children. 
The Bible describes the children of ancient Israel as animals used for burnt offerings, sometimes even to appease the Judeo-Christian God Jehovah. Some scholars have vehemently denied these allegations, although the descriptions in the works that survived from antiquity are just right.
It should be noted, however, that human sacrifices were largely taboo in the majority of Judaeo-Christian religions and violated religious law
The Olmec civilization was one of the oldest large settlements in the world Prehistoric Mesoamerica. Its culture and sphere of influence encompassed much of southern North America, including the area encompassing today's Belize, Costa Rica, El Salvador, Honduras and Guatemala.
The evidence is quite damaging to the Olmecs. It is believed that they are the first known Mesoamerican culture practicing human sacrifice. They are significantly older than other cultures from the early Americas. 
About 300 BC The Olmecs disappeared mysteriously. The damp rainforest ate the bones of the people who had lived there before. All we have left is the remnants of their previous culture.
Nevertheless, there is evidence of child sacrifice in ancient Mesoamerica. Thousands upon thousands of bones have been salvaged in various locations, including the Midnight Terror Cave in Belize and the holy shrine of El Manati. This culture has sacrificed thousands of children to their gods. The bones of these children – along with those of many women – were left behind so that we could find them.
The Mayan civilization emerged some 1,500 years after the Olmec and practiced the practices of human sacrifice also for its gods. Archaeologists digging in the Guatemalan city of Ceibal, which dates back to Mayan culture, have discovered something truly bizarre – obsidian stones buried in the places of their children's sacrifices to their gods.
Obsidian is a kind of darkness of natural glass, usually deep black, that develops when lava cools rapidly. The Maya believed that obsidian is a divine stone.
The Maya sacrifice small children to the gods whom they believed were strengthened by the blood of children. Then the Mayans buried these youths face to face in a grave, often with obsidian. 
What other cultures did on a small scale, the Toltec Civilization did so on a large scale. Over time, many civilizations settled in the southern part of North America, and the Toltecs came shortly before the rule of the Aztecs in today's Mexico. They ruled the area from the 10th to the 12th century AD, and the sacrifice of living children was obviously a staple of their culture. 19659002 Near Tula, Mexico, a mass grave was uncovered during the construction, which contained the remains of at least 24 children. All evidence of this was mass murder and child sacrifice for the gods.
It is believed that the bodies were killed and buried sometime between 950 and 1150 AD.  This was definitely an unusual culture and perhaps gives us an insight into the world of the past and the cruel tendencies of humanity.
The Incas differ from most other Mesoamerican cultures in the world of human sacrifice in the fact that they seemingly sacrificed only children and never adults. This practice continued until the arrival of European settlers.
The strongest and healthiest children were purposely chosen because they should like the gods better. It was an honor in the Inca civilization to be selected as a victim or as a member of that person's family.
Although their population was lower than in other Mesoamerican cultures, the Inca empire was the most widespread (at least 4,000 kilometers). Children's sacrifices clearly permeated the Mesoamerican world of prehistory. The European colonists, for better or worse, endeavored to end these practices upon their arrival, though such rituals were often continued in secret. 
Many Mesoamerican cultures built megalithic structures on which they would bring their macabre human sacrifices. The Moon Pyramid was one such structure in Teotihuacan, Mexico, where the Mesoamerican cultures that lived there long ago would rip the hearts of children and sacrifice them to the gods. The site contains the remains of many children sacrificed by this ancient culture. Strangely enough, the people who lived in Teotihuacan left no clues as to what their culture was about – no hieroglyphics or writing.
As was common in early Mesoamerican cultures, the Teotihuacanos seem to have disappeared, and we can not know exactly why. Centuries later, the Aztecs called Teotihuacan "the city of the gods". The Teotihuacanos had later left their structures completely intact for others to later find.
] As the Roman Empire expanded, it stopped human sacrifice, a practice that was largely taboo in Greek-Roman culture with few exceptions , Most Roman scriptures show that they felt morally superior if they were not interested in human sacrifice. A group that the Romans called the Gauls, otherwise known to us as the Celts, ritually killed children in much of ancient Europe.
The Celts were a brutal but loose group of tribes who occasionally banded together to ward off the invading Romans. In warfare, the Celts would behead their enemies and embalm the severed heads as trophies. Of course, this was also an act of psychological warfare to deter potential enemies.
It should come as no surprise, then, that such a stubborn ethnic group occasionally practices child sacrifices to appease their gods. Roman authors, including Julius Caesar, document extensively the practice and their disgust about it.
Recent excavations of Celtic sites have found mummies of sacrificed children, as well as structures for manmade "fountains of blood", in which blood would be drunk and cannibalism would take place.  The Celts were a terribly violent culture. and these practices show how brutal humanity can be when left to its own means and cultures.
