Cosmic ocean in the context of "Nu (mythology)"

The cosmology of the ancient Near East refers to beliefs about where the universe came from, how it developed, and its physical layout, in the ancient Near East, an area that corresponds with the Middle East today (including Mesopotamia, Egypt, Persia, the Levant, Anatolia, and the Arabian Peninsula). The basic understanding of the world in this region from premodern times included a flat earth, a solid layer or barrier above the sky (the firmament), a cosmic ocean located above the firmament, a region above the cosmic ocean where the gods lived, and a netherworld located at the furthest region in the direction down. Creation myths explained where the universe came from, including which gods created it (and how), as well as how humanity was created. These beliefs are attested as early as the fourth millennium BC and dominated until the modern era, with the only major competing system being the Hellenistic cosmology that developed in Ancient Greece in the mid-1st millennium BC.

Geographically, these views are known from the Mesopotamian cosmologies from Babylonia, Sumer, and Akkad; the Levantine or West Semitic cosmologies from Ugarit and ancient Israel and Judah (the biblical cosmology); the Egyptian cosmology from Ancient Egypt; and the Anatolian cosmologies from the Hittites. This system of cosmology went on to have a profound influence on views in early Greek cosmology, later Jewish cosmology, patristic cosmology, and Islamic cosmology (including Quranic cosmology).

Ancient Egyptian creation myths are the ancient Egyptian accounts of the creation of the world. The Pyramid Texts, tomb wall decorations, and writings, dating back to the Old Kingdom (c. 2700–2200 BC) have provided the majority of information regarding ancient Egyptian creation myths. These myths also form the earliest recorded religious compilations in the world.

The ancient Egyptians had many creator gods and associated legends. Thus, the world or more specifically Egypt was created in diverse ways according to different parts of ancient Egypt. Some versions of the myth indicate spitting, others masturbation, as the act of creation. The earliest god, Ra and/or Atum (both being creator/sun gods), emerged from a chaotic state of the world and gave rise to Shu (air) and Tefnut (moisture), from whose union came Geb (earth) and Nut (sky), who in turn created Osiris, Isis, Set, and Nephthys. An extension to this basic framework was the Osiris myth involving Osiris, his consort Isis, and their son Horus. The murder of Osiris by Set, and the resulting struggle for power, won by Horus, provided a powerful narrative linking the ancient Egyptian ideology of kingship with the creation of the cosmos.

Varaha (Sanskrit: वराह, Varāha, "boar") is the avatar of the Hindu god Vishnu, in the form of a boar. Varaha is generally listed as third in the Dashavatara, the ten principal avatars of Vishnu.

In legend, when the demon Hiranyaksha steals the earth goddess Bhumi and hid her in the primordial waters, Vishnu appears as Varaha to rescue her. Varaha kills Hiranyaksha and retrieves the earth from the cosmic ocean, lifting her on his tusks, and restores her to her place in the universe.

Quranic cosmology is how the Quran views the nature of the cosmos, especially its origins, development, and structure. In the Quran, the cosmos originates in an act of creation by God of the heavens and the earth over the course of six days, with the earth being created first, and the heavens second. The layout of the cosmos includes a solid firmament (called the heaven), below it being a flat earth compared to a spread-out bed. A cosmic ocean is found both above the heaven and below the earth. The number of heavens is seven, with possibly seven earths as well, arranged like a stack of plates. Above the highest heaven is the Throne of God.

In the Quran, cosmology is related to themes of purpose, divine will, and an emphasis on the ordering of the world to allow human beings to live on it.
