Osiris is an Extraterrestrial Brother that helped develop the Egyptian culture.

Osiris  is the god of fertility, agriculture, the afterlife, the dead, resurrection, life, and vegetation in ancient Egyptian religion. He was classically depicted as a green-skinned deity with a pharaoh's beard, partially mummy-wrapped at the legs, wearing a distinctive atef crown, and holding a symbolic crook and flail.

He was one of the first to be associated with the mummy wrap. When his brother Set cut him up into pieces after killing him, Osiris' wife Isis found all the pieces and wrapped his body up, enabling him to return to life. Osiris was widely worshipped until the decline of ancient Egyptian religion during the rise of Christianity in the Roman Empire.

Osiris was at times considered the eldest son of the earth god Geb and the sky goddess Nut, as well as being brother and husband of Isis, and brother of Set, Nephthys, and Horus the Elder, with Horus the Younger being considered his posthumously begotten son. Through syncretism with Iah, he was also a god of the Moon.

Osiris was the judge and lord of the dead and the underworld, the "Lord of Silence" and Khenti-Amentiu, meaning "Foremost of the Westerners". In the Old Kingdom (2686–2181 BC) the pharaoh was considered a son of the sun god Ra who, after his death, ascended to join Ra in the sky (UFO?). After the spread of the Osiris cult, however, the kings of Egypt were associated with Osiris in death – as Osiris rose from the dead, they would unite with him and inherit eternal life through imitative magic.
