Religion is a cultural and social-spiritual system of defined behaviors and rituals, meanings, values, beliefs, ologies, or institutions, which relates humanity to an external or internal source through texts, visions, and rites, that defines humanity as a group of human beings who share a common heritage, mission, and experiences. In general, all religions present a set of ethical and moral questions and answers. However, some religionists may adhere to a monotheistic outlook in which there is only one divine entity, while others may be polytheistic, and even pantheists who believe there are multiple deities or spirits existing in the world and they may not be worshiped or accepted by one religion alone. Additionally, there are also different types of religion such as monotheism (essentially theistic religion), polytheism (polytheistic religion), and freethinking (non-theistic religion).
There are many examples of religious structures throughout history ranging from the earliest archeological evidence to the present day. These examples include such religious structures as the Hindu temple at Rama, Indus Valley civilization, Aztec pyramid, a Mayan pyramid, Greek ruins, and the Easter Island skull mask. These religious structures are manifested in various ways by human beings from all over the world. For instance, some human beings use symbols such as stones, rocks, bells, swords, crests, and feathers to signify different ideals or traits. Similarly, some human beings use icons, glyphs, and sacred texts to interpret the meaning of these symbols. Symbols and artifacts can also represent other concepts such as the concepts of good and evil, love and hate, and the concept of good versus evil.
Some fundamental religions such as Islam, Judaism, Christianity, and Hinduism emphasize on God as the source of all life and knowledge and place human beings between god and man as creatures of god. On the other hand, other religions such as Christianity, Judaism, and Islam stress that Jesus is the son of god and the divine savior, while other non-religious evidences display mankind as creatures of god. The differences in the fundamental religions of Islam, Hinduism, and Christianity illustrate the religious diversity and similarities across domains of human behavior.
