Who was the original deity of Delphi?

The original deity of Delphi was Gaia, the Earth goddess, who was associated with the primordial forces of nature. Later, the site became famous for the oracle of Apollo, who was believed to have taken over the oracle from Gaia. Apollo was worshipped as the god of prophecy, music, and healing, and his presence transformed Delphi into a major religious center in ancient Greece.
