Is the Egyptian God Geb Female?

No. Geb is the male god of the Earth in ancient Egyptian mythology. He is typically depicted as a man with green or dark skin (symbolizing fertile soil and vegetation), often lying prone beneath the sky goddess Nut (his sister/consort), with the air god Shu separating them. His laughter was said to cause earthquakes. As father of Osiris, Isis, Set, and Nephthys, he is a central figure in the Heliopolitan Ennead. The confusion may arise from "Geb" sounding like "geb" (German for "give") or association with the nurturing Earth, but he is unequivocally male in Egyptian texts and iconography.
