Final answer:
Ancient rituals commonly involved sacrifices, varying from animal to human offerings, intended to appease gods or maintain cosmic order, such as in Mesopotamian, Aztec, Greek, and Roman cultures.
Step-by-step explanation:
The common type of ritual among people in ancient times as an offering to God was sacrifice. Sacrificial rituals varied across different civilizations but frequently involved the offering of votive objects, animals, and sometimes even humans to deities. For example, in Mesopotamia, sheep and cattle were sacrificed to supply the gods with food, and temples were filled with gifts to express piety. The Aztecs, on the other hand, practiced human sacrifice to appease their gods and ensure cosmic order, including the famous heart extractions to appease gods like Huitzilopochtli. The Greeks also conducted animal sacrifices outside their temples as part of their religious practices. In Rome, religious practice often centered around prayers, vows, oaths, and sacrifice, and upon fulfilment of a wish, a promise sacrifice or offering would be made to the gods.
