There is no single, universally recognized "goddess of Earth" in mythology. Different cultures and traditions have their own deities associated with the Earth, each with their own unique attributes and roles.

Here are some examples:

* Gaia (Greek): Often considered the primordial goddess of the Earth, she represents the very essence of the planet and is the mother of all life.

* Terra Mater (Roman): The Roman equivalent of Gaia, she is a nurturing and fertile goddess who represents the earth's abundance.

* Mother Earth (Various): This is a more general term used in many cultures to represent the Earth as a source of life and sustenance.

* Pachamama (Inca): This goddess represents the earth as a provider, embodying the power of nature and fertility.

* Ge (Greek): Although not directly associated with the Earth in the same way as Gaia, Ge is a primordial goddess who represents the earth and its fertility.

The specific deity you might be interested in will depend on the cultural context or mythology you are exploring.
