Some religions believe in reincarnation (to come back to life as a different person or even animal). These religions include Buddhism and Hinduism. Hinduism specifically believes that at death the soul leaves the physical body but does not die. It lives in an astral body in an astral plane. Here the soul continues until it is born again in another physical body as a baby. Salvation (called Moksha) in these religions is a release from this endless cycle of re-births.
Most people in the world believe you go to another place after you die, such as heaven or hell. Christianity, Judaism, Islam and Jainism are religions that believe in this. For example, those that follow Christianity believe that if you accept the Christ (Jesus of Nazareth, the son of the Virgin Mary) as your saviour, you will spend eternity in heaven after death; if you do not accept him, you will be separated from him after death.
Many other religions believe in an afterlife of some kind. Ancient Egyptians believed in an `afterlife`. They put things into the graves of important people. These were to be used in the next life. The Vikings had some similar beliefs. Others (like African animists) believe that some people change into spirits called ghosts.
There are also those who do not believe that there is an afterlife, and that you simply cease to exist once you die. Atheists believe there is no God and no afterlife. The Sadducees were a sect of Judaism in the time of Jesus. The believed there was no spirit in man. So, after death there was no more life. .
