Gaia is the ancestral mother of all life: the primal Mother Earth goddess . She is the immediate parent of Uranus (the sky), from whose sexual union she bore the Titans (themselves parents of many of the Olympian gods) and the Giants, and of Pontus (the sea), from whose union she bore the primordial sea gods . Her equivalent in the Roman pantheon was Terra . </P> <P> The Greek name Γαῖα (Gaĩa) is a mostly epic, collateral form of Attic Γῆ (Gê), Doric Γᾶ (Gã, perhaps identical to Δᾶ Dã) meaning "Earth", a word of uncertain origin . Robert S.P. Beekes has suggested a Pre-Greek origin . It, however, could be related to the Avestan word gaiia "life" (cf . gaēθā "(material) world, totality of creatures" and gaēθiia "belonging to, residing in the worldly or material sphere, material") or perhaps to Avestan gairi "mountain". </P>
