Answer:
The practice of human sacrifice in Pre-Columbian cultures, in particular Mesoamerican and South American cultures, is well documented both in the archaeological records and in written sources. The exact ideologies behind child sacrifice in different pre-Columbian cultures are unknown but it is often thought to have been performed to placate certain gods.
Step-by-step explanation:
Mesoamerica
Olmec Culture
Altar 5 from La Venta. The inert were-jaguar baby held by the central figure is seen by some as an indication of child sacrifice. In contrast, its sides show bas-reliefs of humans holding quite lively were-jaguar babies.
Although there is no incontrovertible evidence of child sacrifice in the Olmec civilization, full skeletons of newborn or unborn infants, as well as dismembered femurs and skulls, have been found at the El Manatí sacrificial bog. These bones are associated with sacrificial offerings, particularly wooden busts. It is not known yet how the infants met their deaths.[1]
Some researchers have also associated infant sacrifice with Olmec ritual art showing limp "were-jaguar" babies, most famously in La Venta's Altar 5 (to the right) or Las Limas figure. Definitive answers await further findings.
Maya culture
In 2005 a mass grave of one- to two-year-old sacrificed children was found in the Maya region of Comalcalco. The sacrifices were apparently performed for consecration purposes when building temples at the Comalcalco acropolis.[2]
There are also skulls suggestive of child sacrifice dating to the Maya periods. Mayanists believe that, like the Aztecs, the Maya performed child sacrifice in specific circumstances. For example, infant sacrifice would occur to satisfy supernatural beings who would have eaten the souls of more powerful people.[3] In the Classic period some Maya art that depict the extraction of children's hearts during the ascension to the throne of the new kings, or at the beginnings of the Maya calendar have been studied.[4] In one of these cases, Stela 11 in Piedras Negras, Guatemala, a sacrificed boy can be seen. Other scenes of sacrificed boys are visible on painted jars.
Teotihuacan culture
There is evidence of child sacrifice in Teotihuacano culture. As early as 1906, Leopoldo Batres uncovered burials of children at the four corners of the Pyramid of the Sun. Archaeologists have found newborn skeletons associated with altars, leading some to suspect "deliberate death by infant sacrifice".[5]
Toltec culture
In 2007, archaeologists announced that they had analyzed the remains of 24 children, aged 5 to 15, found buried together with a figurine of Tlaloc. The children, found near the ancient ruins of the Toltec capital of Tula, had been decapitated. The remains have been dated to AD 950 to 1150.
"To try and explain why there are 24 bodies grouped in the same place, well, the only way is to think that there was a human sacrifice", archaeologist Luis Gamboa said.[6]
Aztec culture

Tláloc, as shown in the late 16th century Codex Rios.
Aztec religion is one of the most widely documented pre-Hispanic cultures. Diego Durán in the Book of the Gods and Rites wrote about the religious practices devoted to the water gods, Tlaloc and Chalchiuhtlicue, and a very important part of their annual ritual included the sacrifice of infants and young children.
According to Bernardino de Sahagún, the Aztecs believed that, if sacrifices were not given to Tlaloc, the rain would not come and their crops would not grow. Archaeologists have found the remains of 42 children sacrificed to Tlaloc (and a few to Ehecátl Quetzalcóatl) in the offerings of the Great Pyramid of Tenochtitlan. In every case, the 42 children, mostly males aged around six, were suffering from serious cavities, abscesses or bone infections that would have been painful enough to make them cry continually. Tlaloc required the tears of the young so their tears would wet the earth. As a result, if children did not cry, the priests would sometimes tear off the children's nails before the ritual sacrifice.[7]
