Origins of the Universe
The creation of the universe the Greeks believed in was called Theogony. The creation begins only with chaos, then out of the void appeared Erebus, the unknown place where death dwells, and night. All was empty, silent, endless, and dark. Love was then born beginning of order, from dark, light emerged, followed by Gaea the Earth.
Erebus slept with night, creating Ether, the heavenly light, and to day the earthly light. Night alone created Doom, Fate,Death,Sleep, Dreams, and all things the dwelled in the darkness, that haunts mankind.
The Earth came into existence when Earth was forcibly separated from her consort Heaven (Uranus) for a time so that she might give birth. To effect this separation, Uranus' genitals were severed by his son Cronus ( father of Zeus) and thrown into the sea, where Aphrodite came to be.
Greek Mythology had main beliefs like;
Fate: Greek religions included concepts that could be said to resemble an ultimate reality. Zeus, the mightiest of gods was afraid of fate or destiny. In Greek philosophy, the concept of ultimate reality was emphasized, often at the expense of traditional beliefs about Gods.

Spirits, Monsters and other beings: Greek religion included in the beliefs of mythical creatures that populates their myths. These creatures include: Amazons, female worriers. Keres, evil female spirits. Medusa, female monster with snakes for hair. Satyrs, half men, half goat. Centaurs, half man half horse. Sirense and Typhon.
Death and the After life: Death was not a 'glorious' thing for ancient Greeks. 'The dead are pathetic in their helplessness' they believed. For people who sinned they were sent to Hades, and Tartarus. But Elysium was a paradise for the good. The Greek also believed in Reincarnation.
Gods: The Gods of Ancient Greek, were the described as human in form but with special abilities. Gods were presented as large, multi generational formality, each having their own specific appearance and personality.

Zeus, Hera, Poseidon, Ares, Hermes, Hephaestus, Aphrodite, Athena, Apollo, Artemis, and Hestia, Demeter, Dionysus, and Hades where the variable gods among the 12.
The Ancient Greeks had many rituals to honor Gods. They believed that if they gave the gods something, the Gods would give something back to them. Usually the Greeks would give them something small like a cake of incense, but sometimes large gifts as well, like statues or something personal. An important gift to the Gods was Sacrifice. A group of people would come together to kill an animal near an alter of a God. They would cook it then eat it together. The bones and fat would be burnt for the Gods share. Religious feasting bonded people together and with Gods. whole cities would come together and build temples and giant statues of Gods to honor them.
