Documentary about the history of angels, and their influence on humankind and society both in the past and in modern times. Includes interviews and information about peoples personal experience with angels, such as spirit guides. The origin of angels in history is quite complicated to figure out, due to angels or similar spirit beings being found within many cultures around the globe. Angels are found within three key religions: Judaism, Christianity and Islam. Yet, angels, or divine helpers, were also found within Sumerian, Babylonian, Persian, Egyptian and Greek writings, as well, and played a major influence upon the ideas regarding angels within the key religions themselves. For example, it is well known that ancient Sumerian texts pre-dated the Hebrew book of Genesis, including the idea of the existence of angels. The Hebrew beliefs regarding angels were similarly shared with Christianity, and both Judaism's and Christianity's teachings of angels inspired the Islam beliefs concerning angels. Though maybe called different names, benevolant spirit beings quite similar to angels can also be found within other religions, mythologies, and lore. Hinduism has avatars, Buddhism has devas and bodhisattvas, the Greeks wrote about daimons, and other spirit beings similar to angels, such as guardian spirits and spirit guides, have been taught by tribal cultures. All of these have similar function as helpful spirit messengers, or angels.
