Where do we go when we die?
In some religions, it is believed we go to heaven after die.  There are passages that talk about the pearly gates and being greeted by St. Peter who will check you into heaven and allow to pass through the gates once vetted.  The ancient egyptians believed in three afterlife ideologies; the underworld, eternal life and the rebirth of the soul.  However, for the average person today who does not partake in mummification and ancient egyptians, it is widely believed that once the body dies, the soul leaves and goes to a place of peace.  In a perfect world, we would be reunited with our loved ones, both human and pet, where we would no longer be in pain and can run free with those we care about most.  Alternatively, the more literal answer to this question would be that the physical body either goes into a coffin or some type of container or it is cremated into ashes after death.
