Thoth was a Human under the service of Hathor.
Thoth appeared as a Horus Guard who was in search of a Mastaba (which was a type of tomb) on a moon in the Kaliam galaxy. He was also aligned with the crocodile god known as Sabek.
Thoth arrived to an Unnamed moon, and found a huge chamber containing a Mastaba. He opened the Mastaba awakening the long-time godling Hathor. (Stargate: Rebellion 1)
