At first, there was only the formless, swirling mists of Chaos. From Chaos the first Primordial deities emerged, Tartarus, Gaia, Eros, Erebus, and Nyx. They gave birth to the rest of the Primordial deities. Gaia, the Earth, and Ouranos, the sky, gave birth to the Titans. Cronos, the leader of the Titans, by his sister and wife Rhea gave birth to the Olympian gods. A lot of other stuff happened, but that’s beyond the scope of the Creation myth.
Before the world came to be, there was Nu, an infinite, lifeless see of chaos. Within Nu were the Ogdoad, four gods and four goddesses representing its different aspects. When they converged, the upheaval caused a pyramidal mound to emerge from the sea. Somehow, a lotus flower grew out of the mound and when the flower opened, Ra emerged from it as Khepri, the golden scarab, his aspect as the rising sun. With the first sun rise, the world came to be. Ptah appeared apparently out of nowhere and developed the ideas of everything in the world. He gave them forms when he spoke their names.
Yahweh and maybe a lady or two were lying around when Yahweh got bored and decided to make everything. Everything was underwater for some reason. Yahweh makes everything, apparently fucks up somehow and has to do it all again. This time it seems to stick. Yahweh proves to be a really shitty parent.
Initially there was Muspell, the realm of light and heat, Ginnungagap, the yawning void, and Niflheim, the realm of darkness and cold. When the heat and cold met in Ginnungagap they formed thawing drops that mixed with primordial venom and formed the giant frost ogre Ymir. The thawing drops also formed Audhumla, a giant cow. Audhumla fed Ymir with her milk. The gods Odin, Vili, and Ve killed Ymir and formed the Earth from his body and the seas from his blood. Thus Ginnungagap became Midgard, the land of men.
Roman (The Founding of Rome)
The twins Remus and Romulus were the heirs to the throne of Alba Longa. When they were born, their uncle Amulius had them thrown in the Tiber to die. Through a serious of highly unlikely events, the river carried them to safety. They were then found by a she-wolf sometimes called Lupa. The magic goddess wolf suckled them until they were found by a shepard and his wife. They raised the twins until in true Greco-Roman fashion they killed their uncle and restored their father to the throne. They each wanted to found their new city on a different hill, so the logical solution was to fight to the death and Remus was killed. Romulus founded the city and named it Rome after himself.
