Thousands of years ago, Geb (sometimes, erroneously, referred to as Seb or Keb) was worshipped in lower Egypt as the earth god. Geb was depicted as a bearded man with a goose on his head. He was the provider of crops and a healer. Egyptian people believed that Geb's laughter caused earthquakes. In one Egyptian legend, Geb married Nut, the sky goddess, without asking the powerful Sun god Re (or Ra). Re was so angry at Nut and Geb that he forced their father Shu, the god of air, to separate them. That is why the Earth is divided from the sky. Moreover, Re prevented Nut from having children.
Fortunately, Thoth the divine scribe decided to help her. Thus, he tricked the Moon into playing a game of draughts, where the prize was the Moon's light. Thoth won so much light that the Moon had to add five new days to the official calendar. Thus Nut and Geb could finally have children.
Gaea, or Mother Earth, was the great goddess of the early Greeks. She represented the Earth and was worshipped as the universal mother. In Greek mythology, she created the Universe and gave birth to both the first race of gods (the Titans) and the first humans.
In the creation story of the ancient Greeks, Chaos came before everything else. Chaos was made of Void, Mass, and Darkness in confusion. Then Earth, in the form of Gaea, came into existence. From Mother Earth sprang the starry heavens, in the form of the sky god Ouranos. From Gaea also came the mountains, plains, seas and rivers that make up the Earth as we know it today.
Gaea, or Mother Earth, was the oldest of the gods of the early Greeks. She was known as the supreme goddess by humans and gods alike. She presided over marriages and oaths and was honored as a prophetess.
