Ancient Egyptians were very stricted when it comes to their gods and religious believes. Some of them were convincing and some were unlogical. They had their concepts about death and afterlife journey, and that one's life doesn’t end by his death. The soul leaves the body and go through the death gate to meet god of the dead to judgments. They also believe that the treasures, jewelries and any funeral object that buried with the mummy will be with his in the afterlife. Osiris was the god of the underworld and judge of the dead. He is seen in a lot of Luxor attractions, of the temples and the tombs reflected as green skinned man dressed like a pharaoh. Osiris is not the only god that Egyptians were obsessed about, there are many other god figures like Horus, Amon, Aton, and Anubis.
Luxor attractions are concentrated on two main banks, the west and the east. The west bank is where the funerary temples of well-known pharaohs such as, Hatshepsut temple, the ruins of Amenhoteb III funerary temple and the colossi of Memnon. One of the main Luxor attractions is the valley of the king which is a huge necropolis house tombs of the new kingdom pharaohs like Ramses and Tut Ankh Amun.
