Nefertum

Nefertum was the Goa'uld who brought humans to the planet Bedrosia, creating the Book of Nefertum as a religious text, and forcing them into slavery. The Book explained to the peolpe, falsely, that all life was created on Bedrosia; this belief was continued even after Nefertum left the planet by the Bedrosians, though some people stopped believing this and instead believed that they had been brought through a "mystical portal".
