Use of churchyards as a place of burial After the establishment of the parish as the centre of the Christian spiritual life, the possession of a cemetery, as well as the baptismal font, was a mark of parochial status. During the Middle Ages, religious orders also constructed cemeteries around their churches.

The word cemetery (from Greek κοιμητήριον, “sleeping place”) implies that the land is specifically designated as a burial ground and originally applied to the Roman catacombs. The term graveyard is often used interchangeably with cemetery, but a graveyard primarily refers to a burial ground within a churchyard.

A gravedigger is a cemetery worker who is responsible for digging a grave prior to a funeral service.

A diener is a morgue worker responsible for handling, moving, and cleaning the corpse (though, at some institutions, dieners perform the entire dissection at autopsy). Dieners are also referred to as morgue attendants, autopsy technicians, and other titles that can vary from region to region.

A body bag, also known as a cadaver pouch or human remains pouch (HRP), is a non-porous bag designed to contain a human body, used for the storage and transportation of shrouded corpses. Body bags can also be used for the storage of corpses within morgues.

It takes twenty years to declare a missing person dead. After ten years from someone’s disappearance, a motion to declare the person legally dead can be filed in court. After that, another ten years must pass before the person can be declared legally dead.

A cause of death is determined by a medical examiner. The cause of death is a specific disease or injury, in contrast to the manner of death which is a small number of categories like “natural”, “accident”, “suicide”, and “homicide”, which have different legal implications.

A coroner is a government or judicial official who is empowered to conduct or order an inquest into the manner or cause of death, and to investigate or confirm the identity of an unknown person who has been found dead within the coroner’s jurisdiction.

The possibility of life on Mars is a subject of interest in astrobiology due to its proximity and similarities to Earth. To date, no proof of past or present life has been found on Mars. But, the existence of habitable conditions does not necessarily indicate the presence of life.
