According to wikipedia:
In Greek mythology, the primordial deities are the first generation of gods and goddesses. These deities represented the fundamental forces and physical foundations of the world and were generally not actively worshiped, as they, for the most part, were not given human characteristics; they were instead personifications of places or abstract concepts.
Hesiod, in his Theogony, considers the first beings (after Chaos) to be Gaia, Tartarus, Eros, Erebus, Hemera and Nyx.
