5. HUMAN HISTORY Rainbow Bridge for many decades has been believed to be a sacred religious site for American Indians. Some of the American Indian religions consider arches and bridges to be gateways through which souls enter or leave the earth. Presidents were also effected and touched by this national monument. The reason why we should protect Rain Bridge is because Navajo belief suggests that Rainbow Bridge is a symbol of deities responsible for creating rain, the essence of life in the desert. We should protect it for its cultural purposes, its importance to Navajo culture and also its aesthetic purpose it serves to all people who visit it. The agencies that protect Rainbow bridge are the Glen Canyon National Recreation Area and the EPA (environmental protection agency)
