When we refer to old forms of religion, we refer to evidence of organized form of religions that were practiced based on certain rituals. Ritual burials were in vogue as early as 300,000 years back. In the pre-organized form of worship, ancestor worship played a large role as well. Shamanism was the practice of people going into an altered form or state of consciousness that allowed them to communicate with animals or spirits. The evidence of such forms of practices is seen in cave paintings, some that date back to 320,000 BCE. These practices related to animism as well, which was a belief that all things have a spirit or soul.
Among the ancient organized religions, polytheism was a belief that included several goddesses and gods. Such a practice was seen in several societies such as among the ancient Romans, Greeks, Egyptians, Sumerians and other ancient societies. Most polytheistic religions had similar deities like water deities, mother goddesses, and love and creator deities. Hence, different cultures have similar deities in their ancient religions. Among the oldest religions, Hinduism is a major organized religion in India. It was formed based on different traditions, beliefs, and mythologies across different regions in the country. The two main movements are the cult of Vishnu which is known as Vaishnavism and that of Shiva that is known as Shaivism. Dharma or the ideal way of living is the main doctrine of Hinduism and the belief in karma or the cycle of actions and reactions which result in reincarnation or how the soul moves from one body to another.
